I zoomed through that thread early this morning. Very heartened to see the ratio, massive majority are calm, kind posts saying they fully support this child to dress however they like, name themselves however they like, absolute acceptance to compete with the boys but no, they're a transgirl not a girl and they should not be in female categories for sport. And the attempt to liken it to Rosa Parks was very roundly called out.
I think not that long ago the ratio would have been quite different, it's very nice to see people not usual FWR posters who have no trouble seeing the issue and speaking up for girls. And the only argument really being put is that being trans is such a very hard life that the girls sort of owe their competition to the child as a sort of consolation prize.....which is thoroughly derogatory to every child in the situation!
