Well I've already said how I feel about things when it comes to individuals.
It won't change anything. It's just to make a point.
I mean even if there are people you work with who piss you off for whatever reason. I dunno. I just don't see the mileage in this sort of thing.
Trying to think of another example. Say I was vv RC. A colleague who married in RC and then divorced remarried and took surname.
Would I persist in using previous husband surname for her? Make pointed remarks to other colleagues using her old name?
No of course I wouldn't. If I did and someone got pissy I've got protection religion to wave about.
But I don't see the point of (as I take OP to have done) bringing up their surname for no apparent reason with one of her friends. Friend days wtf that's not on. I think oho and go and post on forum to say my religion terrible etc.
Or maybe that example I should be the one who changed name.
Anyway. Whatever!
It won't change anything.
This person as far as we know has done nothing apart from presumably change name pronouns clothes.
I mean I can't get worked up about that at all. If just getting on with things and not in women's spaces.
Not all trans people are awful by default.
I find this petty and nasty really.
And it achieves zero. Apart from maybe making a perfectly nice but not confident person feel like shit if/ when they find out.
Also doing this sort of stuff will make us seem like arseholes. There are people who will gradually change their mind. Trans people who think the colonisation of women's everything are becoming more in number and being blunt, on Twitter at least.
Going around being petty and mean about individuals we know, just because they're trans. Will not win us any friends. Quite the reverse. It will make those who might support in time, away.
