Not too long ago there was a discussion on another popular forum about the possibility of people being able to change their gender without medical intervention.
There were a couple of posts about how it seemed like a good idea, it was a huge step forward for trans rights, how they didn't understand why people would care because it doesn't affect them, etc.
Another poster then came on and pointed out that wasn't strictly true and gave a few examples of how it could hurt other people. They remained polite and civil. They didn't threaten anyone or call anyone any names. However this poster was still branded a transphobic bigot and an evil TERF and had their words twisted around by other posters to try and make them look bad.
One of the potential problems she brought up was the possibility of men being able to change gender in order to access women in toilets and the like in order to hurt them. Despite making it clear that she was talking about men who wanted to hurt women using the law to their advantage to basically take the piss, she still had people twist her words around to make it sound like she was saying transwomen were all predators and a threat. So what happens on here basically.
Interestingly enough, there was also a transwoman on that thread who didn't think the proposed bill was a good idea and also discussed rationally why they thought that and also pointed out that it was open to abuse. The people yelling TERF at the previous poster though didn't really engage with the transwoman though; they mostly just ignored them. So again pretty much what happens on here when a transwoman shows up.
I am yet to see a so-called TERF threatening anyone or hurting anyone yet I see them accused of it all the time. I do see lots of threats from transacrivists towards TERF's though, apparently as a result of being pushed to their limits by all those so-called mean TERF's. Pushed to their limits of what though? Groups of women wanting to meet and talk about issues that affect them? Why is that so threatening to anyone? They're not hurting anyone by simply meeting up and having a discussion.
