The world chess federation FIDE recently made the incredibly transphobic and mysogynist ruling to exclude trans women from competing in women's tournaments, to strip trans men of pre-transition titles and to subject trans people to a two-year long surveilance process that could lead to forced outings. The German and French chess federation have now decided to ignore this ruling. Source in German (mostly with the info from the image): https://www.queer.de/detail.php?article_id=46744
And not too long ago there was an open letter denouncing the rampant abuse and assault that including trans women as signatories. There couldn't be a more blatant example of transmisogyny's function in destroying feminist solidarity and defending patriarchy.
