You challenge ignorance with ignore-ance. It's the core idea of the word. Ignore stupidity. If you engage it as if it were a rational, thinking being, you lose.
The only ignorance and stupidity is ignoring the fact incorrect returns are being posted. Sadly, instead of being adults and respectful to those highlighting this error, you yield to name calling which is very Trump of you. It's sad Santafe, after all these years on the planet, you still haven't learned to be respectful. Grow up, man.
