First of all im not really a woman or someone who supports woman idiotic choices , so my points won't be women centered but reality centered.

We all have that one friend who is a nerd , avg or below avg looking who thinks niceness allows him certain freedoms or benefits but these guys are universally disliked even by men as being too weak , pushy cats and afraid.

Then if these men had looked around they would have found that the most succesful people the billionares, politicians , corporate overlords etc are not nice but either good looking or smart or charismatic or born lucky . In no time was we told that nice guys would succed in society leave alone a women pants .

In most films which did showed this the man was also good looking and the women liked him first as a friend and then shifted to love entrance after hengot a glow up . The last film I watched on this topic had clearly had the male lead as a tall attractive guy who just looked dumb cause of his fashion sense.

Most often these men just have nice world fallacy and have nothing much going for themselves so use thier niceness which is also a form of cowardness in a lot of times as a sort of bargain position.

Lastly niceness isn't even a trait in sims
