A coward? Coming from an ex marine? That's rich.
You seem to be suffering from what is known as 'dick out' syndrome, in that you must, under all circumstances, be right and have others believe so as well; otherwise your sense of self seems to be quite threatened.
But when you cannot counter the claims against the logical flaws in your argumentation, you offer to argue any topic at all, just for another chance to prove to yourself that your rhetoric and skill at at discourse aren't as flimsy as rice paper.
Tilt on, Don Quixote.
