After I saw the picture from your post my first thought was, I'd walk up to this guy, and say "you are NOT an idiot".

:)

On the topic of not disparaging people that we disagree with, one of my favourite quotes is from Ravi Zacharias, he is a famous Christian apologist, he says when we are debating one another we have to ask ourselves whether our aim is, the winning of the person or the decimation of the person?

He went on to argue that no person should ever ridicule a person, and that if you are doing so that you have already pushed them beyond the realm of reasonable dialogue and perhaps being convinced to your point.

So are you just trying to humiliate them, ridicule and laugh at them? Or are you trying to convince them of a point you feel is valuable and valid?

Good post, upvote, resteemed and followed.
