This whole thing is stupid. How is an evil character being gay negative to gays anyway? Good lord. Evil straight people don't really matter.
The worry was that since there are so few gay characters in games and other media already (though we've been making some progress within the past few years) there would be negative connotations to having a gay character in a widely-played AAA game also be a badly-written psychopath.
You also have to consider that equating homosexuality with villainy is a pretty old trope in fiction. There's a common trend in media where being gay is treated as a "symptom" of villainy - as if being gay makes you inherently more perverted and immoral than straight folk... Incidentally, there's also a common trend to emphasize feminine traits in villainous characters. Since being gay is commonly misunderstood as making men more effeminate the two see a lot of overlap.
People calling out those who
did jump to conclusions might understand things better if they considered how common these stereotypes are. Those who are often subjected to baseless stereotypes about themselves tend to be more sensitive to even the slightest suggestion of them... Yeah, it led to wild and baseless speculation here but that sensitivity is a direct result of living in a social climate that is often misunderstanding and prejudiced against a crucial and inseverable part of your identity... I don't even think I participated in that conversation but I won't apologize for worrying that he
was gay and I don't think others should either.
