I have a traditional catholic friend whom I have known for about 4 years.  We have kids about the same age and we have slowly gotten to know them better.  But we have never been invited to their house. We either saw each other at church or invited them to our house.  I knew they were living with relatives, so I just figured they were trying to be considerate of them. But recently we were at an event where we met their nephew. He is eighteen or nineteen years old.  It was obvious by the way he dressed that he was gαy, he even had a rainbow bracelet and his eyebrows drawn on.  They didn’t introduce us, he was just there. Now I wonder if they never invited us over for that reason. I know they have raised him from a young child, so I think they are enabling him.  I am not sure if I should just ignore it, or if I should be asking some questions, or reconsidering our friendship entirely. My main worry is that her kids are being raised with him, so some form of normalization is there. How will it effect my kids when they play together? We were planning to meet up regularly and even go on vacation together.  I wouldn’t let my kids read books or watch shows that normalize gαyness, so what about friends? What would you do? 

Definitely keep younger children away from him. fαɢɢօts are, per capita, disproportionately pedophiles compared to heterosɛҳuąƖs. Pedophilia is secretly tolerated in fαɢɢօt culture and community, and there's a term, "chicken hawks", that's used non-judgmentally and humorously within the fαɢɢօt community to refer to the pedos.

The proportions of heterosɛҳuąƖ and ɧoɱosɛҳųαƖ pedophiles among sex offenders against children: an exploratory study. https://www.ncbi.nlm.nih.gov/pubmed/1556756

Abstract
Previous investigations have indicated that the ratio of sex offenders against female children vs. offenders against male children is approximately 2:1, while the ratio of gynephiles to androphiles among the general population is approximately 20:1. The present study investigated whether the etiology of preferred partner sex among pedophiles is related to the etiology of preferred partner sex among males preferring adult partners. Using phallometric test sensitivities to calculate the proportion of true pedophiles among various groups of sex offenders against children, and taking into consideration previously reported mean numbers of victims per offender group, the ratio of heterosɛҳuąƖ to ɧoɱosɛҳųαƖ pedophiles was calculated to be approximately 11:1. This suggests that the resulting proportion of true pedophiles among persons with a ɧoɱosɛҳųαƖ erotic development is greater than that in persons who develop heterosɛҳuąƖly. This, of course, would not indicate that androphilic males have a greater propensity to offend against children.

Regarding the very last sentence in the abstract, it's merely a subjective opinion, and it was likely inserted so the study would not be blacklisted by politically correct shills and social-engineers. However, the stats & findings are quantitative and very telling.

It certainly seems prudent to distance the children from them.

But as adults, if you're close enough, probably worth talking about with them.  If you've been friends for four years and haven't had any red flags go up yet, that tells you that either they're convincing sociopaths or that they are ashamed of their nephew and want to pretend that he isn't the way he is and have no idea what to do about it.  Now I'm guessing they're not sociopaths, so they could probably use some support.  Maybe you're not the person to give it to them, but maybe you are.

@Nadir, why wouldn’t you call him gαy? Are you saying that there is no such thing? As in God made us to follow his will, and anything else is just perversion?  Or are you saying that everything together just constitutes a troubled teen?

gαy means happy.  The word has been hijacked by ɧoɱosɛҳųαƖs to try and "soften" the perception others have of them.  It doesn't sound nasty to be gαy. 
 
It does sound nasty to be a sodomite, which is what a ɧoɱosɛҳųαƖ male is in fact.

So don't be swayed by political correctness!  Just as abortion is not "birth control", ɧoɱosɛҳųαƖs are not "gαy".

If when didn't introduce you to her nephew then it is likely that she is ashamed of him and only tolerates him. This is a sad situation that requires our prayers more than our intrusive questions. I think the best option is to say nothing directly and to not ask questions that would tend to make the situation worse.  

There is little in this world more creepy and inherently disturbing than an openly feminine-acting sodomite.  Seriously, most of the people that hate sodomites are people that spend the most time around them, contrary to the narrative.

It goes much deeper than that. Male-on-male pedophilia is fetishized within the fαɢɢօt sub-culture almost as much as male-on-male rape is.  Every time you see some scandal about rape in the US Army (which is a huge thing, by the way, nice job never mentioning it,mainstream media) it's almost always a sodomite raping a weaker looking, usually short or scrawny, male.  Men are naturally dominant, as God intends, but because the lifestyle of the sodomite is an affront to His order, that dominance manifests in the worse, most perverse way possible.  

The horror stories I've both read and heard of senior soldiers/officers, picking out some weak-looking guy, that they often safely assume lacks the spine to fight back, and violating him on an almost daily basis, are unbelievable.  They have no mercy. Those that do not immediately repent should literally be burnt alive, and I'm not even kidding.

Excellent contribution. Thanks for the posting.

I think I will try to answer questions in one post. I have never met the nephew before, so he has not been to mass that I know of. He was homeschooled. I know he has a job now, so that may have been influential in his choices. My friend is a catholic convert, so she was Protestant before. All the family that live close to them are Protestant as well, and they sound enmeshed. 
I can see my friend being ashamed of her nephew. I know they have commented that they don’t agree with his choices, but since he is not their child they don’t feel they can enforce standards the way they can with their kids.  Not knowing what they meant specifically I guessed they were talking about him coming to mass.  They also mentioned that since the house they were living in was not their house they couldn’t lay down the law.  I personally don’t agree with either of those statements. Either he needs to adhere to their standards or live with a different relative. And I would not live where I had to subvert my catholic faith. I understand they sold the home they lived in so they could care for another family member in their home. 
 I have noticed a few red flags, but mostly it was the enmeshment and lack of boundaries with her family.  
  My hubby doesn’t know them quite as well as I do, so he wants to know more first. I think he is planning to speak to the husband.
