How dare they?

I see that Mr. Yglesias is outraged that some idiot DC suburbanites wouldn’t want a light rail importing “riffraff” into their neighborhoods. While I don’t know enough as to the specific nature of the riffraff, or ruffians or hoodlooms or hooligans and suchlike in question, I can only guess as to why residents of Chevy Chase wouldn’t embrace the happy effects that, say, the Baltimore light rail has had on Owings Mills and Timonium.
