Oh please! You asked up thread if any of us had trans friends. If you weren't so new here you'd know tha the answer to that is a fairly resounding yes. It is also possible that an acual trans person is one of the posters responding to you - there are a few and they don't always feel the need to share their trans status!
The problem is that you are were many of us were a few years ago, me included: Be nice, inclusive, transwomen may not actually be real women but it doesn't hurt to include them. We all rubbed along, women pretended not to notice, swallowed their feelings of unease, and nobody rocked the boat.
Then came the TRAs. They changed things dramatically. Some women pointed it out about a decade ago and most people reacted as you are now. But over the last few years thing have changed. Aggressive transwomen have made huge incursions, done much damage to women in female spaces. That is real women being hurt, physically, by men claiming to 'feel like a woman'.
So no. I won't feel ashamed at saying, consistently and ever more loudly, transwomen are not women and cannot be given free access to female spaces. This has to be a discussion, not a fait accompli so shut the fuck up, stop throwing out the insults and threats and start talking.
You see, it is not me, or posters like me, who are partially informed or who should feel ashamed of our views. You may, over the next couple of months, if you stick around and read and try to digest what is really being said here, come to change your mind.
If you look through many FWR threads you will see many posters, me included, post exactly as you are now. So I know some of how you feel, what you are thinking, why you are thinking it. Then you will see a different thread... a lightbulb moment. I wonder what it will take for you. Karen White doesn't seem to have, so what will it take? How many women will be hurt, raped by transwomen, reported in headlines, discussed here, before you will stop seeing any discussion of that as transphobic?
