To me the quotation implies that the speaker of the quotation has assumed the right to judge whether other people have really gifted kids, or are putting tap shoes on elephants. In my reading, it doesn't say "I'm not hothousing"-- it says "stop hothousing YOUR kid, because you're being ridiculous, you'll never make them gifted."
Which may or may not be true. But in my view, judging other people's parenting is pretty much fraught with peril, and the condescension of the quotation is perhaps unnecessarily provocative.

I think the reader would have to view the statement through the polarized lens of their own insecurities to come to the conclusion that they had been judged with disapproval.
