Last month, Andrew Pessin made an invaluable demonstration of how Jews endorsing some position does not remove that position's anti-semitism. I would like to add to the discussion about Jew-washing by drawing an analogy to general racism. Consider the case of voter-ID laws which several red states have passed. These laws disproportionately affect African-Americans who are more likely to lack the identification required under those laws. There are those who suggest that the laws are intentionally discriminatory
UPDATE: I initially forgot to conclude the analogy I was developing, here is the conclusion. Just as conservative African-American endorsement of voter-ID laws, such as from Clarence Thomas, would not change those laws from being discriminatory to non-discriminatory, so too does Jewish support for BDS have no effect on its being anti-semitic.
