John Constantine can date a guy for a year (in-world or 12 issues) and have on-panel sexual relations and there's still going to be folks who're all, "He's just doing it... for the job/because he's bored/in a not gay way..."
Kitty Pryde is licking frosting off another woman, telling her she's completely in her hands, and the artist can actually call it a lesbian seduction... there are people who insist it isn't really gay, she's not anything but straight straight lalalacan'thearyou straight.
You can't convince everyone. Not in a world where people legitimately have training camps to ungay people or believe in "hate the sin not the sinner" applying to homosexuality as equally as to theft or murder (but not disrespecting parents or forgetting the sabbath, because those are hard to not do sometimes; being not-gay is a cakewalk).
