I would imagine they've been told to "be kind" and that any issues raised will be treated as a transphobic hate crime, seems the usual way of things.
Good point. Who organised this, and are the members of Dulwich's team free to opt out?
On the face of it, it doesn’t look like any sort of a league game, so there’s nothing to stop any team playing whoever they like, whether it’s Women’s, mens or trans.
Yes, teams should be free to do what they like. But if they are in any way compelling female players to play against male players, then we have an issue.
And given the histrionics around this sort of thing, I have a sneaking suspicion players may not feel free to decline.
