Well, Matthew, your initial post didn't even mention the possibility of people losing babies early or not being able to conceive.
This is a sensitive issue because most people don't know that a woman is having a hard time conceiving or is losing babies in the first trimester unless she or the husband share their sorrow with others. It's been a sensitive issue for me at times when I knew that a couple were having these difficult issues and some nosey busy body assumed that the couple was using birth control.
Yes, even Traditional Catholics assume these things and then an assumption that is voiced turns into gossip and pretty soon, so many people believe it and don't realize that it was somebody's assumption to begin with. The accusation becomes "common knowledge" and is whispered around causing scandal. Please, folks, be careful of your assumptions.
One tradtional Catholic relative had a tragic end to a very difficult delivery and that was the end to having any more children so after having a small family, they grieved for the others that they would never have. Over the years I have set a few mutual aquaintances straight when they gossiped that this couple was using birth control. How hurtful is that kind of accusation? I just hope the couple never knew what busy bodies were believing and spreading. If only that were the only time I've heard this type of talk.
I know other situations where couples had miscarriage after miscarriage or simply couldn't get pregnant. One poor woman was reduced to tears when a Traditional Catholic busy body went right up to her after church and said "You know that it's wrong for you to put off having children." The poor couple had been desperately praying for a baby for a few years. She began crying and went to get her husband and they both left and I wondered if they'd ever come back. Thank goodness they did come back to church, but the husband had strong words for the busy body and she was pretty embarrassed when she found out the real situation, but do you think that caused her to stop thinking the worst of folks? Nah.
I wish I could say that's the only time that I know of this happening, but it's not. I've been around in tradtional Catholic parishes for a long time. Please folks, ALWAYS THINK the BEST of OTHERS. If you can't do that, then pray for them. If you are blessed with lots of kids I'm sure that you thank God for them every day. We were very blessed ourselves, and the grandkids keep coming, but I have been in a position to know of others' pain and I can tell you that it's a very deep sorrow. Let us all pray for others and make it a habit.
