Is your question/objection rhetorical, or did you just not understand the A Human's Guide to Words sequence?

Taboo "person", and if that doesn't work, taboo "raise children", and if that still doesn't work, taboo "no matter the IQ" or "can do" or "reasonably well" or even the entire list of symbols that is generating the confusion.

I objected and gave a thought experiment to illustrate the falsifiability of one specific assertion, which can be nothing else than what I believed you meant by that list of symbols, based on my prior beliefs on what the symbols represented in empirical conceptspace.

If you question my objection on the grounds of using a symbol incorrectly, then you should question the symbol usage, not the objection as a whole through a straw-manned assertion built with your different version of the symbol.
