Oh look they're erasing women again.
Plenty of women have fled Britain in fear of "forced adoption" to countries like Ireland and France where the legal system regarding removal of children at birth doesn't work the same way, but obviously they don't count, their experiences aren't real, because they're just women.
I'm not saying these women were right to do it or that they necessarily deserved to keep their children (that's a whole separate thing), but what I'm saying is, there's been cases of women fleeing abroad because they believe they won't have the right to keep their child, and this is just leaving the country due to perception anyway.
So no, trans people aren't the "first" to leave the country because of their perception that they don't feel safe here, if we ignore the dramatic posturing of unrealistic legal asylum cases. They're just hanging on women's coat tails again and erasing women in the process.
