I don't like using the term verbal abuse. And I don't personally believe telling someone when they're being stupid (not ignorant) and that they're behaving idiotically in a tone that is slightly harsh, qualifies as verbal abuse. But to each their own. And as Kick said, the debate were having is pretty clearly illustrated. Show complete loving tolerance, show irritable intolerance, or ignore all together. I personally believe all 3 are useful, but it all depends on the circumstance.
