Serious question: while both are considered "vulgar", why is calling a man a prick less offensive

[Caliman73]

36. I never said that men are expected to act like pricks.

Merely that they can do so without suffering significant consequences whereas women who try to act aggressively like a man, are often penalized for it in significant ways. When they behave in a neutral or feminine way, there are told that they are too weak to achieve success except for those areas where they are allowed.

The question that the OP asked was whether the two words were equivalent and if not then why not? My answer was social power. Men have it, women do not.
