Women find it to be a threat to them.
As my wife explained it...women grow up in competition with each other for everything from clothing, appearance, boyfriends, attention. They view us as the "competition" and invariably compare themselves to us. If we are thinner, have nicer hair (even if it's a wig), look better in a certain style ... we are the enemy...
We don't see it that way, but they do. I'm not saying all, but certainly a lot and particularly if you are in a relationship with them.
