The language of the complaint is borderline incomprehensible and it looks an awful lot like trolling. But even if it isn't, the complaint is obviously dumb and, as a gay man, I actually find the complaint offensive. It's fine for a straight character to flirt with the PC and proposition him/her, but it's inappropriate stereotyping if a gay character does it? And, as mentioned, how can it possibly be stereotyping gay people as a uniform whole when it has another gay character who doesn't proposition the PC. Additional note: It's true that not all homosexual men make such advances and that some of them just want to settle down in a nice white-picket-fence neighborhood and assimilate. Some of us don't want that. At all. When you force all of the homosexuals in a game to be demure and to avoid "forcing" their homosexuality on anyone (which is already a silly phrase for anything but rape), you're being just as homophobic. In a way, you're being worse: you're not objecting to same-sex relationships, you're passing judgment on an entire culture, an entire culture that you're at least tangentially a part of.
Also, online petitions are pointless. Why do people keep doing this?
TL;DR: The stupidity is almost palpable.
