When someone refuses to play a game after hearing one, insignificant or at least not particularly big part of the game that they didn't like.
For christs sake, sure, as an example, I am a hater of yaoi(boy on boy manga/anime), the themes I've seen in all the examples presented to be only include things I think should not be mixed up with relationships and sex(like, physical and psycological abuse) so therefor I don't like it.
But just because I don't like yaoi doesn't mean that automatically everything that includes gay people is shit and not worth my time(this goes for real life situations as well, hell, my uncle's gay). I didn't throw away Dragon Age because you can have sex with Zevran as a male character.
