I have seen KJK confront TRAs on a number of occasions and she has never resorted to personal attacks. She doesn't need to.
Yes, I've noticed that she doesn't swear. I don't know if she doesn't swear in real life, but she makes a point of not doing so publicly.
If this person was trans, them asking Posie what was on her T-shirt was, of course, going to be goady.
Her answer was what her answer always is. TWANW. And, for the poster upthread who doesn't get it, she is within her extremely hard fought for legal right to say so.
Perhaps the driver had not encountered a woman who doesn't give a flying fuck before.
Either way, it's completely inappropriate to attempt to engage her on a political viewpoint with which he clearly disagrees.
And deliberately intimidating her by saying he would leave in his own time, is completely unacceptable.
