Eugene Volokh at The Volokh Conspiracy has a good post on anti-Communism and the ACLU.
It may be fairly said that VDARE.com has tended to stress the disadvantages which go with immigration, rather than the advantages. (It's our job, after all.)
But one thing that immigrants (Professor Volokh left Russia at the age of seven) have more of than native-born Americans is genuine, heartfelt anti-Communism.
