Yeah, research like the fraudulent "gay gene". The old "science" label, the most effective propaganda tool in use today.

"There has been no single gene identified as a basis for sexuality - either homo or hetero. If you would like links to various research efforts that have been, and are currently being, done on determining the basis for sexuality, i'd be happy to provide them."

I didn't say there was, just a fraudulent claim there was by some sodomite "scientist" desperate for acceptance.
Had enough propaganda on the subject in psychology class."

Goodness knows people make claims all the time that are not backed by actual science. The one you mentioned is an example, as is the claim by some that sexuality has been proven to have no genetic basis. Those claims, however, do not change the fact that the basis for sexuality is unknown. What 'propaganda on the subject' did you receive in psychology class?"
