The editorial board of the New York Times is frothing at the mouth about immigration. If you're not in favor of open borders (i.e., if you believe in borders), you're a "racialist extremist," a "nativist," an "anti-immigration absolutist," a "Latino-basher," a "xenophobe," a "racist," and a "white supremacist." How edifying. This doesn't even reach the level of playground name-calling. It is the moral equivalent of screaming.
Addendum: Here is a video of Peter Brimelow.
