Completely agree with this. People say homophobia can be presented as a character flaw, but frankly there’s lots of other ways in the setting you can explore themes of bigotry that don’t have the same real-world connotations and also have an actual basis in lore.
The existence of homophobia in the Warcraft setting is a headcanon, and a heavily loaded one at that. Admittedly Blizzard’s LGBTQ+ representation in WoW is pretty lacklustre at best, but the few examples we do have of gay characters aren’t derided or treated any differently.
