You can use the word "sane" to mean anything you want it to. As you well know, since you're the one who brought that long, detailed previous thread into this one, the meaning I'm giving it "not based on cosmetic features like grips and barrel shrouds". The basis for my argument is factual, and you should concede that, because you yourself set the tone and expectation of rigor on this thread, and you aren't living up to that standard.
That I'm not even advocating for that particular proposal is besides the point. You accused me of arguing in bad faith, and I am now pointing out that it's in fact you that are doing that now. It's an easy problem to correct; you simply have to say "I was wrong about that, let's move on".
