Discussion of Transphobia, Women and a CervixWatch
It's pretty basic-level transphobia to assert that no trans man is a man. If you don't care about transphobia or think it justified then just be honest and admit it.
We've seen this style of argument over and over for years, just with different forms of prejudice: "It's not (racist/homophobic/transphobic/other form of bigotry) to say do (X)!" The argument, either implicitly or explicitly, is not really "X does not meet the definition of racism at a qualitative level", but rather "Racism is bad, but I think X is good/justified, so therefore it can't be racist!"
Odd these people think they are liberal, crazy eh?
