> Apparently Mark Twain never said it.

The advice has been written and uttered in various forms for millennia.

> If the quote stated "If you are ignorant on a topic it's better not to discuss it" that would be advise. (Though less quippy).

Your quote would be different advice; it doesn't have the same meaning nor implications.

> But I read the quote as essentially saying: "You are so incredibly stupid you should never, ever attempt to speak to another human being ever again, on any conceivable subject".

How many of your personal experiences are you reading into a context-free aphorism of the ages? Friendly suggestion: you may be making this same mistake when interpreting words in other situations.

"Your quote would be different advice; it doesn't have the same meaning nor implications."

What meanings or implications does the aphorism have other than "some people (fools in this case) shouldn't ever talk?"

We've established you think I've misinterpreted the aphorism and that you suspect there's something socially off with me, but we haven't established what you think the aphorism means. Go on, educate me.
