Here is a funny video about gay scientists looking for a Christian gene.
I am not sure what point the producer was trying to make. It looks like a parody of Christian scientists looking for a gay gene. But I thought that it was mainly gay scientists who promote the gay gene theory. Maybe it is a parody of gay scientists looking for a gay gene.
I am not sure which is more ridiculous, a gay gene or a Christian gene. Most behavior is some complex combination of nature and nuture, as far as anyone knows.
