The beauty of the X-Men, and Hermione for that matter, is that it's an allegory for anything. It can be about being gay or civil rights or da shoah or literally any trait a person can exhibit that receives societal pushback. By operating as a metaphor, both the authors and the readership are able to project a whole array of subjects onto the same concept, and because none of them are explicitly mentioned rather than implied, it all works and they all exist in a state of superposition.
I checked some panels people said that it proved he was gay all along and of course it was all in their heads.
The alleged scene is him taking Rogue home to meet his parents (they aren't dating, she's just there for the road trip) after he already took other girls, one of them Asian. Not only the dad is a bigot ("first an Asian, then a...", Bobby assumes he's gonna say "mutant", but maybe he was gonna say "redneck", who knows), but the whole point is not Bobby's girls, but rather that nothing Bobby does is enough for the old guy. It wasn't about him being gay or dating non whites or being a mutant. It's simply that he can't please his father and the father's too hard to please and he can't be his own person because of it.
That's much more relatable than being gay, imo.
There is another panel when later Mr. Drake tells someone (Cyclops? Gambit?), when he's at the hospital after some attack, the old "and have you tried not act like a mutant? Because you don't look like". He gets told something like "I joined the Xmen so I/we shouldn't have to".
Considering many of them are orphans or stranded from their families, it's Bobby's role to have an antagonist family in general, something most young readers can relate too. It was a mistake making it about being gay because the story was more like "my father has impossible standards so I should just be me".
I'm not sure if Dani Moonstar is actually gay, or that's something they decided to throw in there, in New Mutants.
I googled, and fuck it. She is a lesbian now. Not a fan of the NM, but I hate Marvel.
ETA: Bobby and Rogue's road trip is famously another "clue" of him being gay for the most stupid reason. Rogue's brokenhearted bcuz of Gambit, so that's why she leaves with Bobby, who's her friend and he's trying to comfort her. So, because she's wearing a small top and shorts and he's not all over her, he's gay. Fuck the fact that they're friends, that he knows she loves Gambit, or that he can die if he touches her and be very likely doesn't want to die. Not being a borderline predator is evidence of homosexuality, said by the same "me too" crowd.
