How a man treats his mom says a lot

I used to think that a lot because that's what everyone would tell me and with that I started judging way to harshly men who said they don't have a relationship with their mom or say they don't fuck with their mom. I used to think how dare you cut your mother off and treat her that way. Or refer to her as a bitch. Someone who brought you life. Then... I made a friend. He was a guy, but we were dating. I asked what was he getting his mom for mother's day and he said "That bitch can die". I was shocked and horrified. I ended up going off on him like "Do you know the pain that women have to go through to bring children into this world. Yet boys want to disrespect their Mama's". I was going off on how wrong he is and he cut me off and said "My mom beat me, tried to run me over with a car, chased me with a knife, all before the age of 16". I apologized... I was literally like holy fuck. Maybe I was naive because I have good parents. GREAT parents even. Well now I'm less judgement. If a guy or anyone says they don't have a relationship with their mom or has bad things to say I simply ask why. I have gotten some dumb answers but honestly most of them or completely justified. And if they say they don't want to talk about it 8/10 it's still usually justified. So just because a guy(or anyone) doesn't have a relationship with their mom or good things to say DOES NOT MEAN THEY WONT TREAT YOU RIGHT!!! And honestly after reading some of these mil stories on here it's probably best to get with someone who actually cuts a parent off when they're too abusive and toxic.
