A belief derived from feminist ideology that women, no matter their
sexual orientation, should not be heterosexual because men are
the enemy - in their eyes. It is fairly
controversial, as it's typically used as a tool for horny lesbians to trick straight women into hooking up with them. Another controversial aspect is the fact that it is saying you can choose your sexual orientation, something the gay community definitely does not agree with.
Political Lesbianism is probably something
Rachel Maddow and
Rosie O'Donnell have used to get into straight
women's pants.
