It is well known that the vast majority of terrible people lack the self awareness. They'll find excuses for any wrong doing/shortcomings and blame society humanity manhood feminity or whatever but themselves. That's how you spot one

If you recognise yourself in those following logics then chances are that you suck

"As a man, dating is difficult so it is okay to take any opportunity even if that means misleading the girl"

"Girls/women are responsible for being mislead/used, all they need to do is to wait longer and vet men better"

"A man cheating isnt near as bad as a woman cheating because we are hornier and it's evolutionary psychology for men to spread our seed"

"I used to envy partying and some forms of casual sex , didnt get to participate and now i feel a moral upstanding over those who did"

"Personnality doesnt matter. Women love assholes."

Here are a few for my ladies

"Men only want sex"

"I am the table"

"He should know better, i shouldnt have to tell him"

"Seeing having sex as doing your man a favor"

Bargaining sex

Trying to push your man to see how he'll react and other shit tests or stuff to trigger jealousy

"He couldnt please me so i cheated"

Now if you recognise yourself in those kind of twisted logics, please take the hint. If you have other examples feel free to share
