These athletes that are mad about trans people in sports are universally the middle of the pack "also ran" losers.
Like, yes, you lost a random marathon to a trans woman, sure. But you also lost to like 71 other people out of the 200 people in the thing so the whole "stolen victory" thing they all try to play is nonsense. A trans person competing did not make the difference between you coming in first and you coming in 38th.
