An anonymous commenter at Sailer’s wrote “[H]ow many straight men with Ivy League educations enjoy the opera? […] In my estimation, the type of man who enjoys the opera is typically gay and is therefore definitely not the type who would want to marry a woman with an Ivy League education.”
Again, this seems amenable to the gss.

Gay men do seem to be more opera-loving than straights, although also prone to more extreme responses. I was surprised how much lesbians dislike opera. Straight women like it more than straight men, but they still seem to be closer to their potential mates than they are to gay men. As for the commenter’s statement, it neglects the base rate. An individual man who likes opera is probably straight, because there are simply a lot more total straights (even atypical ones) than gays.

We can also look to see whether people have attended a performance of classical music or opera.

I don’t have time to do much analysis before heading off, but I’m surprised again by lesbians so often seeing such performances given their dislike of opera. I guess they must really like classical. There should be a GSS question for that.
UPDATE:
The question for classical music is CLASSICL. Here are men’s responses.

The association of folk with lesbians was mentioned below. That question, appropriately enough, is FOLK. Here are men’s responses.
