Yes @Bizawit we do knw, we have eyes!
If you read round here for a while you'll find a lot of posters, I'm one of them, who came here and said exactly that and got a lot of more or less robust repsonses that added up to - think about the difference between transwomen, individuals that we all know that use the ladies and TRA actions.
Transwomen use the ladies loos. Women see them and, being knd and all that, think "transwoman, be nice!, maybe smile a bit, but don't make a fuss, poor thing". We all move on with our lives.
So you see why it is the ladies loos that TRAs always distil the argument down to. So they can say "But transwomen already use the ladies loos!"
What they don't say, or want discussed, is everything else.
Start with an easy one - male bodied individuals in women's sports!
Women say no! Biology!
TRAs shout TERF and some poor science is wheeled out!
You only have to watch transwomen compete against women to know. However partisan you are, however nice and inclusive you want to be, however little you actually care... any picture, any sport.
