Dont call cps, thats a huge hassle and can ruin the kids life worse than anything. Be a man and confront him yourself. Ill say this though, my dad beat me, the physical pain didnt affect me, what did affect me was emotional pains of my parents trying to mold me to thier idea of a child and not listining to me ,these things werent why I was beat though, I was usually beat over some dumb shit.. A beating aint nothing compared to that stuff. Plus a fun fact - My high school principle would use a paddle on students (if parents signed off on it) instead of suspensions. Alot a kids got paddled. This was Tennessee but still, it was in the 2000s.
