The problem with insults in America is that people confuse sexism for insults that are gender-specific. Unlike anal sex, many insults do not work on any gender.

Many of the insults we men use on each other just don't work on a woman. For example, what would calling a woman a "dickless wonder" even mean?

Similarly, let's say I wanted to insult a guy raised by a gay male couple. It would make no sense telling him "Your mother is a whore".
