In case any one of my conservative friends are looking for examples of what Liberals are calling the coarsening of the dialog, Townhall Magazine just named their "50 Most Dangerous Liberals." There's an interesting example. A "mainstream" publication (put to bed before the shooting this past weekend, so there was no chance to change the headline) that lists liberals as "dangerous." Not, "strongest liberal voices" or "liberal movers and shakers," no, they have to (again) demonize the opposition and raise the "red flag" for conservatives. Those liberals, see, they're dangerous. Just like criminals.
Sure, a banal example, but again, a magazine meant for mass consumption and they can't keep from this kind of rhetoric. Unlike, say, a memo or internal communications that can be a bit more unguarded, this is meant to be in the public sphere.
I guess I should be happy they didn't add either "unpatriotic" or "non-American" to the title.
