Now obviously this is a bunch of bullshit, but let's consider this claim when taken to the extreme, by conducting a thought experiment.
Everyone here has a few dream women they would love to date if they had the chance. Just suppose, hypothetically, that your dream woman actually turned out to be a biological male, but still keeping everything else true about their appearance, in every exact way.
Then, in that case, would you still date them? Or would you choose not to simply for that one difference?
