Funny thing about both of those articles: none of those have any references to liberals. And "liberal arts" doesn't count.
Anti-semitism is its own problem. Don't go dragging a partisan blood feud into it.
The 'liberals are anti-semites' accusation seems to be a talking point these days amongst some cons. According to G-man's article things are getting better, with incidents of anti-semitism down. And using G-man's reasoning, the liberals should get the credit for that drop. (that is if we were using his argument logically )
On a serious, note I hate the tactic of smearing a broad group (like lib or con) with something terrible and then offer up fuzzy rationalizing.
