You make some fair points, so I'll try to hit what I think are the key ones. Also, if you reply to me and want to continue the discussion, please @ me so that I see that you replied to me.
What is bigotry?
Bigotry is intolerant and single-minded devotion to one's own arbitrary ideological prejudices, disgust-responses, or irrational beliefs.
Surely you can see the difference?
Sure I can, but what if I was a racist who believed that black skin was repulsive, and so discriminated against blacks? The point of my example was to illustrate that disgust is itself not a criterion by which to judge moral questions like the worth of persons or the moral permissibility of certain kinds of sexual acts.
The permissibility of sex in the person's view may have nothing to do with how disgusting he finds it. I asked about a person who has a moral objection the homosexuality. Though you did not call him a bigot, you described a bigot. Just as Keith did.
I was responding to the question (also the title of this thread) you posed first, namely: "is repulsion at the homosexual act bigotry?" Nowhere in that question, or in any of the questions of the OP, do you mention a "moral" objection.
My answer to that first question is "no," because one can be repulsed by something, but still not allow their views of it to be defined in terms of their repulsion. A person repulsed by heterosexual sex could still come to believe that heterosexual sex is perfectly okay to engage in and that heterosexual people are of equal worth to him/her. In such a case, the persons disgust is not allowed to dictate the way they conceive of heterosexual sex.
A moral objection to gay sex, to answer your new question, is not bigotry per se, unless it is rooted in disgust (thereby conflating disgust with moral reasons/justifications), arbitrary ideological prejudices, or irrational beliefs.
