That two, or three, or more grown adult men lustfully gorging themselves on one another, or sexually sating one another via any of their orifices, or romantically kissing or showing any other form of romantic affection is somehow not deviant, perverse, and grossly self-indulgent behavior - or that two, or three, or more grown adult men lustfully gorging themselves on one another, or sexually sating one another via any of their orifices, or romantically kissing or showing any other form of romantic affection is somehow "normal" behavior is what needs now to be demonstrated.
It's my assertion such behaviors are deviant, perverse, and grossly self-indulgent.
Deviant because two (or more) men do not normally behave thus - we're not even physically designed for such behavior.
Perverse because two (or more) men behaving thus constitutes a turning away from or rejection of what is right, good, and / or proper. It's wicked and corrupt.
Grossly self indulgent because two (or more) men behaving thus is taking lustful self-indulgence to an extreme.
My authority, my "proof" of this comes from the bible. Like it or not, believe it or not, accept it or not, that's my "proof." It's not my opinion, it's God's opinion. It's not up to me to "dictate" anything. He has clearly asserted such behaviors abominable and worse. And the thing is, because HE says it - that is what makes it fact - though even a modicum of common sense would work as well.
Now you may disagree - you may say these are my opinions - you may say I have no "proof" - but such assertions themselves demand proof. Unless you are willing to do what Agent J clearly isn't and demonstrate how such behaviors are "normal" or otherwise NOT deviant, perverse, or grossly self-indulgent, your arguments are not better than what you claim of mine.
