As a former DM, the edition matters not for the adventure. The DM is in full control. If the DM says the Drow is racist then he is. Whatever lore is written in whatever books of whatever edition are irrelevant to what the DM says. That's why I'm fine to play any edition of D&D because the edition is irrelevant to the role-playing experience if the DM is competent. If any player has a problem, they can get fucked because they aren't the DM.
WoTC is insulting the original creators of D&D. Musk got that right.
