Well Gaider seemed to make quite the sensible response to the homophobe. I can also understand the position of 'bastal' since I come from a hick-town where gays were hated and an open gay attacked just being himself and trying to flirt at the local bar. Bastal isn't comfortable with gay-love between a man and his male character, it just offends and strikes him as wrong. Disgust is a good marker of what we consider immoral and if it is as he says, he was being a good leader and kept getting flirtation from men, it really could become quite the annoyance. "No Anders, you are a valued member of the team, I... I don't think of you like that. Bloody hell man, what is it with you, does the blood smear on my face turn you on?" Yeah, could be funny for us and frustrating to him.
I suppose he could solo it on easy or only go for female party members, maybe that could be a solution in this world of bisexuality.
Or perhaps he misses the good old days of patriarchy and sexism as personified by Korgan. Korgan was quite the filthy little dude, my favourite team member, utter psycho, reliable as a back-up axe. Perhaps this is what balstar is missing, uncomplicated straight characters to fight by his side.
Bioware won't do it, but for the radical homophobe, they could add the option of killing a flirting party member out of shame and disgust (and a little arousal). Let's see how the party deals with that, and the dwarf narrates that one! Don't take me too seriously people, just an idea.
