Matthew Yglesias and Kevin Drum both comment on a survey that Republicans think, by a margin of 61-39, that homosexuality is caused by upbringing; whereas Democrats opt for genes by a margin of 66-34.

This confirms a throwaway comment I read a few years ago, I think in the context of the Bell Curve debate. Conservatives think that everything except being gay is determined by the genes and Liberals think nothing but being gay is caused by genes. There’s a moral there somewhere.

Update: MacDiva has some comments.
