I think it'd be more accurate to say that he feels that not every human is TREATED equally. Especially where sex and intimate relationships are concerned.

When I was younger, a lot of guys wondered how so many really scummy guys could get lots and lots of beautiful women ??? I did too. After many years I've come to realize that... well... sex and intimate relationships just might work differently than polite society believes they do.

There are probably entire industries built on exploiting the chasm between propriety and desire.
