That's a pretty ridiculous claim. I'm clearly not going to convince you of anything, but for anyone following this thread you can read http://www.troubleandstrife.org/new-articles/you-are-killing... for what I found was a level-headed explanation of the divide between trans activists and the so called "TERF"s.
"TERF" is no more of a slur than "Neo-Nazi" or "rapist", and all those groups are the scum of the earth.
There is no moral difference between a TERF and a member of Stormfront or a known rapist.
