Keeping toxic people in your life, regardless of their gender, is not something that somehow makes you a better or stronger person. And most psychologists with licenses agree.
And it's important to accept those things we cannot change, lest they torment us.
The animus in the culture right now is divided between those who have some acceptance of their fathers, and those who don't. It's not just a right/left thing either, as that animus decides whether someone chooses to be an unworthy person who blames, betrays, and justifies their own cruelty to others because of what they imagine they suffered themselves - or not. Understand who he was and consider that a lot of the anger at "The World," was really just pent up anger at him. Personally, I think a key role of a father is to moderate the urges for cruelty, vanity, conceit, self pity, and other vices that mothers often overlook and forgive, and mainly by example.
Sorry, but this pseudo-intellectual nonsense.
Granted, some children who don't "accept who their fathers were" fall into the borderline spectrum that you're referring to. Or are needlessly resentful of their parents due to simple human failings, such as a single lapse of judgement at some key moment. Of course.
But a very significant portion have perfectly valid reasons for "not accepting who their fathers were". And it would be psychologically unhealthy for them to try to force themselves to do so.
Any more than any other victim of violent (or comparable) crime needs to "accept their attacker for who they were". Or force themselves to "understand" their attacker's motives. Let alone forgive them for anything.
Are their children supposed to "accept" him regardless, and feel bad about themselves if they can't?
