I don't think ALL men are angry at women, but there are many men who resent women for rejecting them or ghosting them etc. But the reality why she rejected you is because she has a superior option available: a man better than you for her needs in every single way. Men should realize a woman wanting the best is for herself is perfectly fine - who wouldn't want the best partner, career, life for themselves??

A man superior to you out-competed you for the same woman. That is who you should be angry at. Same situation for the college you didn't get in, or job that you wanted -- someone ELSE out-competed you and took your spot.
