Wow. There's that double standard where classic Trek is immune from criticism, but modern Trek must answer for its sins. DS9 presented an all new look for the Trill which was not consistent with what we saw on TNG and offered no explanation whatsoever. Hell, more time has gone by than the twenty-five years and two months which elapsed when Enterprise explained the TMP Klingons, which That Crowd claim makes it okay. So why is fandom so lenient about DS9's changes to the Trill, but Disco changes the Klingons and it's all "not Canon!
