Words fail.
I know what you mean, but let me try.
No study huh? How about the study of human existence. The fact that we are by nature and design meant to be hetrosexual.
Basic human biology.
Therefore being repulsed by homosexuality would be the correct response to ensure the survival of the species.
Anything less would/should be considered a defect.
Where the hell did these people go to school?
And yet heterosexual men are drawn to "lipstick lesbians."
You would no doubt claim that is because two women double a mans chance to procreate.
How do you explain the proliferation of oral and anal sex among heterosexuals? Is that not against nature and design as well?
The guy quoted obviously doesn't want to be bothered by the facts. He says the behavior engenders universal revulsion but he doesn't yet know if it is "biologically based".
That's like saying in all cultures there is a revulsion to eating sh!t but we're not yet sure if the aversion to eating sh!t is "biologically based" or not.
The contradictions are astounding but even more so because they exist in successive sentences.
