I agree with you 100%. I understand that gay people have grievances against the majority—some valid, others not—and I see no issue with games incorporating that. In a standard game, the protagonist could even be an extreme nymphomaniac (or the male equivalent); I don't mind. What matters to me is that the character is well-written and that their sexual traits are justified by the story. In that case, I’d have no problem playing a character who is vastly different from me and with whom I can't identify—unless the difference is too extreme, in which case I probably wouldn't (which is also normal; if there isn't a single point of connection, then we have a problem).

Thanks :).
