bohemian rap siddhimy hypothesis about argumentation is that most arguments/debates revolve almost entirely around semantics and are almost always about feelings more than anything. this is why i hate when people say "that's just semantics" and also why i laugh when i hear a-weasle-i-wil-not-bother-naming say "facts don't care about your feelings," as if the "facts" he uses to argue are not, like everyone's when they argue, chosen because they support his feelings.
and yes, this is predicated on the idea that belief and doubt are feelings. i personally can't imagine what else you'd call them, but i'm willing to discuss it.
also, i've given you zero explaination of the semantics part, which is actually the part i feel more solid on, but in fairness it's damn hard to explain.
