Loner, did you actually say "Eew"? I noticed that your original post was edited. If so, yeah, that was a pretty mean thing to do- but we're all human, and I bet there isn't anyone reading this who can say they've never done something mean, intentionally or otherwise.
That aside, I don't see why everyone's in such a tizzy because she felt uncomfortable... I mean, I work at a bar, and a lot of significantly older men approach me, and sometimes I think it's funny... but other times it makes me uncomfortable. Why? Because I'm not accustomed to that. How is it any different here?
I'm uncomfortable on my first day of school- because it's something I'm not used to. I was a little uncomfortable at first in the inner-city neighborhood I moved to, because it has higher crime rates than my old neighborhood. I'm uncomfortable the first few days of a new job, because I'm not used to it yet... but none of this implies hatred toward the new situation.
I don't see how not being interested in dating another female makes someone homophobic, or how being uncomfortable in that situation does, either. LOL, I chose to go to school for nursing rather than verterinary technology- that doesn't make me an animal-phobe! I just decided which I would rather do- but even if it was a decision between nursing and say, business, which I have absolutely no interest in.... I don't see how saying 'no' to business school, or feeling uncomfortable at the prospect of it, makes me 'hateful.'
Anyway, I don't see this so much as a matter of being made uncomfortable simply because someone is different- I am not uncomfortable with the differing views on abortion, to use Opeth's example. But I would be hesitatant- uncomfortable, indeed- about accepting an invitation from either side to go demonstrate. It's just not my thing. And if being gay is just not someone's thing, I can't see accusing them of being hateful.
