whenever I hear SJW's whining about male-centric society:
Dude, either out yourself as an incel or go and read up about why relationships commonly fail / reasons for infidelity, such as "since the baby was born I feel like she loves the baby more than me" or "I wanted to get some but she was pregnant".
Selfishness is gender-specific in relationships. That sounds totally plausible!
That's aside from the fact that child / animal abuse exists and (when it does) commonly occurs within a family unit.
