FWIW I come from a non working class background ( but am not American ). My friends and I routinely debate in such a manner, and don’t see any problem with this. If confronted with a stranger we might be a bit more cautious ( basically we’ll state the rules of the conversation) but that’s about it. If needed, we’ll sometimes be a bit more accurate.
I understand your statements as you mean them - I default to giving you the benefit of the doubt, and automatically assume that black and white statements are shortcuts. Only, and only if you seem to not understand nuance then I will adjust my stance, but I usually assume you do!
I think the problem can be described as assuming good faith in the argument - that is, that you're talking with someone who you are presuming is attempting to communicate, not just "win" the conversation.
The difference becomes clear very quickly - if there's a genuine misunderstanding, someone will clarify and move on; if someone is trying to rules lawyer the conversation, it won't.
