This thread's a great demonstration of coercive control that underpins this whole ideology:
You will affirm, you will call this vulnerable young woman a man because I demand you do. If you don't you're a bad person, a transphobe, you'll be alienated from your family etc etc.
The positive thing is that people are now refusing to be bullied. Are insisting on speaking up and trying to protect the young and vulnerable who for too long were abandoned and left in the clutches of the trans extremists seeking to use them for their own purposes
And this needs to be said.
The behaviour of the OPs SIL is not good. The OP says that they behave in a way that's something that should be talked about more.
I always say it's fine for the do going interferers who know fuck all to tell you how you should behave if you have a family member do this. They know nothing.
It is like a grenade being thrown into a family.
We need to remember how many families have dysfunction relationships and wholly unacceptable behaviour.
I always say to don't respond to the identity. Be conscious of behaviour. That's what should guide you.
What you shouldn't do is tolerate behaviour you wouldnt tolerate from someone who isn't trans.
The OPs SIL is clearly deeply troubled. That doesn't mean she shouldnt be held to account for coercive behaviour. Nor should family members pander to unreasonable demands. Unreasonable demands remain unreasonable regardless of identity.
If we are talking about equality then this is really relevant. We actually treat people the same. And if someone acts like a dickhead, we respond to this accordingly. We don't just roll over and pander to it.
