To think being a “nice guy” is often just repressed entitlement?

[WrySilverDrake]

They’re not nice - they’re just scared to be rejected, and when they are, it all comes out.

i am guessing/ hoping you don't have a son brother father male partner or any other male family members in your life as you clearly including those men in this sweeping statement

You have misunderstood.

There is a type of man who describe themselves as a 'nice guy' and then rant about how horrible women are. Meaning that women aren't falling over themselves to have sex with them.
