Sounds like you and your kids need to do some workshops. I personally don’t think some of the parents of the children that attend our church could care less what their kids are watching. I fear some have seen it all and not just over an iphone. Flipping the bird in church is nothing and this is rural America.
Well, I’ve certainly never witnessed “flipping the bird” or anything like that at our Latin Mass or at the ‘regular’ Mass or at the Southern Baptist church down the street. In fact, a few parents are stricter than us and totally ban tv, videos, etc, at home. We don’t ban them but keep a close eye and block the known bad stuff. However, I have never seen one single attempt to bypass any of the blocks and I was a former national software administrator and not much gets by me.
