Why do people always blame the mother for the father being a deadbeat

I wanna have a serious question. I be on Facebook just scrolling and I see all types of crazy shit. My question is

Why do people blame the mother for the Father being Absent/Deadbeat. They always bashing the mothers but I hardly See ANYBODY Say anything about the father. Like he gets a Pass. It’s always the mothers fault , she should’ve never opened her legs , she should’ve knew and all that silly shit

Well he should of knew what he was doing , he had 9 whole months he knew was what was coming he should have no Excuse. Ok you can’t force a father to stay but don’t blame it on the Ladies. He should take the blame for not having responsibilities. Ain’t that’s the main thing off life having responsibilities.

To me that’s wrong I don’t like that.
