As several of my online contacts who often are wiser in this than me "Arguing on youtube is like a turd slinging contest between chimps."
I don't know how many times the arrogance, ignorance, plain stupidity, or just plain asshole-ness of the slew of idiots occupying Youtube comment section has gotten to me after I just posted my own opinion or an observation.
Giving some people Internet access has allowed them to spread their own brain damage to the rest of the world.
