You guys are probably sick of my bitching, so this'll be it.

Hm. Easiest solution, really, is to ignore them, save up, and move out ASAP. There's a world of difference in how they argue and guilt-trip you when they can't claim to be feeding, clothing, or sheltering you anymore, and dear God does it feel amazing. Just an idea. Work on this first if those trips aren't all that urgent, because, afterwards, you'll be able to make all of those choices - and more - without them breathing down your neck.

No, it isn't. Because this way, the issue remains open, a source of conflict between you and the other person, instead of something you could talk through with them and hopefully reach some sort of agreement on. And then another argument occurs about it later.

It is not unreasonable to be hurt by vicious words.

EDIT: Anyway, it's midnight for me and I probably shouldn't debate or argue or whatever on this just now.

You misread or misunderstand the point. Do words hurt? Sure they can, but are words just expressions of feelings. Given words being expressions of another person you suggest that the feelings of others hold power over you. That too is normal. What is not normal is to encourage unhealthy individuals to continue what they are dong to get what they want because it works.
