Sounds like the cause is neurological since a stroke is unlikely to alter your genes lol.

It would be easy to spot in before and after brain scans but it's unlikely he ever had a scan done before this happened so meh...

Still they should be able to tell what parts of the brain were damaged and compare results with the brains of healthy gay men.

Truth is, it would be really easy to discover the true cause and nature of homosexuality if we really got down to it, but nobody wants an answer that invalidates their beliefs lol.

Gays don't want to hear they may be mentally ill or brain damaged or an evolutionary dead end lol.

Religious types don't want to hear that it may be a perfectly natural occurance like genes because that means GOD made them gay lmao!

Humans... So fucking weird.
