I haven't read all these replies, so forgive me if I repeat something that has already been said.
After coming to tradition and SSPX from the modern worldliness of Protestantism and Novus Ordo, I found most people to be fairly niave regarding the ways of the world.
At first I found this quite refreshing. But when an incident occurred with our best friends that could have been prevented if only people knew the signs of ɧoɱosɛҳųαƖity and perversion, I realized that this naivetee is very dangerous not only to the children and parents but also to the priests as well.
A priest today simply cannot be too "friendly" toward the children outside the presence of the parents. This is just a terribly sad fact. A great many trad priests don't understand this and often offer to give classes for this or that or take the children on some field trip, etc. Unfortunately this opens up the portal of accusations and suspicion. There have been any number of priests wrongly accused of misconduct. I know of two who were accused of intoxicating young boys and possibly taking advantage of them. None of this was true, of course, but the entire scandal could have been avoided. We do not live in the 19th century.
Parents today just cannot trust anyone. I am sorry to say that, but you just can't. We must be on guard constantly. We are VERY cautious about where our children go and who they go with. Fortunately my husband has access to criminal records and mental health records. He checks everybody we know. Everybody. On many occasions, without violating anyone's privacy, I have warned parents to rethink allowing their children to go to certain people's homes.
Ultimately we are responsible for our children's welfare.
I might also add, just because someone is a trad priest, it does not mean that they are trustworthy with your kids. Be cautious.
Also, I don't know if this is an issue in SSPX or even FSSP, but in independent circles some of the priests were once NO priests, have left for various reasons, and have been conditionally ordained by some bishop somewhere. I caution people always, always, always, to check these priests out before trusting their children with them. Some of these priests have been removed from their NO dioceses for terrible acts and have gravitated toward tradition because they like the bells and smells and because trad parents are often very naive. It makes their young boys easy prey.
In regards to the report, my biggest question seems to be why in the world a parent would allow a child to travel on the road alone with a truck driver?
Please, parents, do not check your brain at the door around traditional Catholics. They are not immune to sinful thoughts and behaviors! We have a duty to protect our kids!
