The internet, and the world in general is full of morons who are most notably morons for the simple fact they are too stupid to realize how stupid they are. These idiots provide a foundation for frustration and confusion for the average person who is still, on the whole, pretty darn stupid.
I find this hilarious and sad. In my life, I've spoken with a lot of different people and sat (or stood) and listened to a lot of different conversations. So so so so so many people have this exact same thought of the rest of the world, but not themselves. Everyone is stupid... Except the person who's saying it.
I don't agree. I think that people lack humility, yes, and people are focused on being right, yes, but stupidity is not the reason for the flamewars. The reasons are simple: a lack of humility and Confirmation Bias (a concept everyone should look up).
I only make a comment because I feel that the "everyone else is stupid" argument is not just pointless, but detrimental to any kind of getting along, anywhere, and in any context.
I do like your points about Keyboard Warriors, though.

I'm curious, too. Are you trying to win by DTing?
