Anti-semitism on campuses is up. Could be because professors teaching at major colleges are linked to terrorist organizations.

An annual audit by the New York-based ADL found 106 acts of anti-Semitism on campuses in 2002, a 24 percent increase from the 85 a year before. The total number of anti-Jewish incidents increased by 8 percent, from 1,432 in 2001 to 1,559 last year.

The ADL said the anti-Semitism acts on campuses included name-calling and damage to buildings housing Jewish fraternal organizations. Anti-Israel rallies that didn't lead to overt episodes of anti-Semitism were not included in the audit.

How do you quantify if an anti-Israeli rally contributes to anti-semitic acts?
