Fore the most part, DUers and Moonbats in general live in bubbles ( communities of the like minded) , echo chambers ( tv, the internet, media). and as a rule don't like to mix with others who have different ideas, or different lifestyles then themselves.
But if you go by the DU thread presented, The DUers are most intolerent, small mind people I've seen.
Fore me, the people I meet are like a gallery of paintings, each different and unique.
The Moonbats on the other hand want to be in a house of mirrors; everyone is just a reflexion of themselves.
