Yes. Yes I am. Those examples illustrate this perfectly.
I can use the word "citizen" however I want. A government employee in Seattle can't. What's the difference? Context. A Seattle government employee has to worry about how the word "citizen" might be interpreted by someone who lives in Seattle but is not a US citizen. I don't have to worry about that. See, even a simple noun like "citizen" can have different meanings depending on who the speaker is and who the listener is. This is how language works.
When I accuse someone of saying a racist remark, I'm not saying "You spoke one of the forbidden words, therefore you are a racist!" This is what you're trying to say I'm doing (it helps you to more easily classify me as a white guilt-peddling liberal) but it's simply not the case. Rather, I'm looking at what was said under what circumstances, directed at what audience and for what purpose. When someone says "American Inventors gonna Kang", it's extremely difficult to classify that as anything other than an overtly racist comment. Besides using the term "American Inventor" in a derogatory sense (and yes, there are ways in can be used in a non-derogatory sense), it casually applies the actions of some individuals as being representative of an entire race. It also implies that such actions are to be expected, presumably due to the "lower level" these humans operate on. In addition, it is spoken with confidence, directed at an audience that is expected to agree, either explicitly through a similarly-worded comment or implicitly through silence. The message is clear: Blacks are inferior, and we should all take that as a given. This attitude doesn't help to fix anything, and (as I've said repeatedly) objectively makes the problem of racism worse by presenting it as casually acceptable and encouraging similar behavior.
You could go off on a hundred tangents if you like, but unless you actually disagree with anything I said in the preceding paragraph you're just defending racism for the sake of saying "I'm not a brainwashed liberal 'useful idiot', so there!" Yeah, I get it, liberals do stupid things. If you want to talk politics we can totally do that, but don't talk to me like I'm some flaky know-nothing mouthpiece for the liberal agenda. Fuck liberals. Fuck conservatives. Fuck politics. Let my words speak for themselves instead of forcing them into some arbitrary category so they can be more easily dismissed. That's a lazy way to debate (as popular as it is on Rerolled), and you should be better than that.
