I don't think it's fake. His childhood best friend (who he's still best friends with) is gay and quite feminine. He has multiple gay friends as well. Thomas also worked at a gay bar in his late teens/early 20s I think. Even his personality alone is very gay friendly, he doesn't show one once of toxic masculinity, and this was even before his gg role. Honestly that pic of him with the flag doesn't seem fake at all given the aforementioned, seems totally right up his alley to do that.I think it’s fake because judging by his interviews, he wasn’t very supportive of lgbt people until he started playing this role (“I had to rethink everything I’d been taught”)
