I have to interject here. Bigotry is "intolerance toward those who hold different opinions from oneself." I would expand that to "conditions". It has nothing to do with politesse. Bigotry is prejudice - "preconceived opinion that is not based on reason or actual experience." His positions are definitionally prejudice with regard to gender, race, and sexual orientation. He may not be overtly antagonistic, but that does not excuse the underlying bigotry.
Let me take this as a starting point to pinpoint what I think is a problem. Tolerance of different points of view does not mean agreement, nor approval. It means letting people express themselves, presumably with a genuine attempt at engaging the arguments people make as opposed to falling back on personal attacks. Now, ask yourself this question very seriously:
Is there any way a religious person could consider homosexuality sinful without you considering them to be bigotted?
Here, we should be charitable and assume that the hypothetical religious person involved here believes that homosexuality is a sin. However, they insist on it being a personal choice and on not interfering. If their opinions are requested in a discussion, they will state it, but they will not otherwise interfere in your life and they will never treat you as anything less than a person. If it conflicts too much with your view of religious people, you can imagine that I talking about someone who is unusually morally upstanding.
Now, here is the point of that game. Many conservatives believe that when concepts such as "bigotry" or "hate speech" are being expressed, they are synonymous with the disagreement of the left. I'm sure it's somewhat of an exaggeration, though I have seen enough people make use of insults frivolously to target conservatives (and get away with it) to suspect it might not be entirely false. If you cannot find anything our hypothetical religious person could do, or say that would allow them to condemn homosexuality without being considered bigotted in spite of having picked the softest religious person I could imagine, then you argue that some aspects of religiosity, conservatism, and bigotry are one and the same thing. If, on the other hand, you manage to find some line between tolerance and approbation, between bigotry and disagreement, then you agree with conservatives that you can legitimately disagree on issues as deeply personal as sexuality and have a very civil discussion over it.
My answer:
Although I do not see any particular reason to condemn homosexuality myself, I do understand that tolerance and approbation are different. The first word says something about what
you do not do. Tolerating differences is a fancy way to say "live and let live." It doesn't mean you like what other people do, or that you think anyone should be doing it. In fact, you might strongly object to it and still be tolerant. For religious people, scripture and traditions carry with them wisdom about how to best live your life. The morals behind stories that we bothered dragging with ourselves for millennia are not without their reasons to be compelling. One of them is that it survived for so long and tackles aspects of our human experience that didn't change much. Some people drag from it that homosexuality should not be pursued and I am not ready to call this completely prejudicial.
The line I trace between a religious bigot and a religious person isn't a political line. If you thought through the view presented in your scripture about family, marriage, and sexuality, and if you bother discussing those views with people who have firsthand experience, I cannot call that prejudice because you took the time to dig. I wouldn't say that my approbation of homosexuality as a legitimate way to conduct one's life is less prejudiced than the view of many people who disapprove of it. At the moral level, the overriding criterion in that case for me is that I couldn't imagine myself not being with a woman, so I don't see how we could demand the equivalent on their part. However, that's just an intuition. All the people I mentioned have much more to say than I do about this, so how are they more bigotted than me?
