Invalid argument: You're not a woman

I love how often, when people say this, they say it as if they are bringing new information to the table. As if they have discovered something that no one else is aware of. As if they have just seen through my clever disguise, and point their accusatory index finger against and say "AHA! You're not a REAL woman"

Well I have never claimed to be a woman, and I've never really felt a need to claim to be a woman, because if something is true when a woman says it, it is true when a man says it. Truth is not related to the gender of the one who speaks it.

I'll some times feel emboldened to speak on moral issues that concern women. Such as for example abortion. If abortion is wrong, it doesn't become right because I'm a man and can't become pregnant. So it seems strange to bring that up in an abortion debate. It would be similar to saying that black people are disqualified from saying slavery is wrong because they didn't qualify to own slaves.
