Seems like a huge claim you can’t backup due it being a negative.

Yeah in a world where dogs can smell cancer and people with relatively mild brain injury can wake up permanently speaking in a different accent I think it's entirely possible that a radical change in microbiome due to freak accident or experimental treatment has resulted in a change in sexual preferences.

Interesting because people also used to say sexual preference was genetic

Not strictly genetic, certainly, but in at least one configuration there is a clear effect that is perhaps genetic in the mother:

It certainly has a heritable component. When people say "the way you're born", do they mean something non-genetic? What would that be?

There are lots of pre-natal environmental influences on “the way you’re born”, its not just genetics.

What do they say now?

Who?

I wanted to make it easy for you to disprove iff it does not holding - lack of such disprovals only strenghten my point.
