I guess I don't think that the meaning of my question was hidden in any significant way. This is leads me to interpret your response less as a genuine concern for specificity that lead to constructive criticism, and more as "I don't like this subject—therefore I will express disagreement with something you did to indicate that." It feels to me as if you're avoiding the subject in favor of nitpicking.

I know you knew what the actual question is because you pointed out vagueness. You knew the question you answered [Literally: Do different races have different brains?] was not the question I intended. Regardless, you didn't attempt to answer the question or really address it at all. Instead, you pointed out a way it could be misinterpreted if someone took the effort to avoid all context and assume I was asking a nonsensical question (which people do not usually do, unless there's some political-esque intent behind it).

My apologies if you have a genuine concern regarding the specificity of my question—but I implore you to try to answer the actual question, anyway.
