Our boys have attended Catholic grade school and high school (largely due to the dire condition of our local public schools in our city.) My oldest doesn’t relate to the religious aspects while my youngest is very much involved. Both are treated exactly the same at their school. In fact, our list leans heavily towards Catholic Universities out here on the West Coast, with most being Jesuit, due to the respectful nature we’ve experienced so far. BTW, I’m definitely NOT Catholic, though my wife is. I have personally found their schools to be inclusive and not in the least preachy so far.
