Okay, back the truck up. Nobody wants true and independent thought, otherwise we would have to redefine ourselves as all human. I mean we all know that straight people are one kind of human and gay people are another kind of human. They are completely different in physiology as well as philosophy, so there is no way there could possibly be straight guys who enjoy ass play--that automatically makes you gay. Which would mean that if there are any of you gay men out there who don't like ass play, there is no question you are only fooling yourselves no matter how many men you sleep with!
I mean the point to this is obviously to define who is pure and who is not based on sexual activity. Experimental and curious actions or passions do not play a role in self-definition. So its simple, if you fool around with others outside of your designated socio-sexual definition or in ways others would not, you are obviously not pure. Now that we have reached such a grand conclusion I am sure the Natzis would be very proud. Crank up the ovens!
