the only argument i have against ace enjolras is that hugo chose to compare him to more than one gay figure from classical antiquity. to me thats a clear indicator that enjolras is at the very least leaning towards being gay.
Also like… Ace people can be gay?
But… at the time, when Hugo wrote it, he wouldn’t have had the same understanding of what asexuality is, so he probably wouldn’t have written a character specifically believing them to be asexual… or at least, knowing what it meant.
I think it’s a perfectly valid interpretation to have nowadays – especially given that it’s canon he has not so much as kissed another person – but I think at the time, Hugo was coding him as gay very explicitly, so even if you regard him as Ace as well, you can’t just ignore that. Enjolras is gay.
