No, mentioning the ADL isn't antisemitic per se, nor is it necessarily antisemitic to say anything critical about the power Jews wield in this country, isn't it. However, when you mention a person's or a group's religious belonging when you discuss how wealthy or powerful they are, the context tends to be racist. Try to imagine you're talking about Muslims rather than Jews. Are you willing to apply the same strict PC standards to Jews you apply to virtually any other religious affiliation?

All that notwithstanding, it's a whole different ball game when a proven antisemite like JA does it in a certain context, then it is antisemitic.

You should do some rudimentary homework before you make such sweeping statements. The JDL does NOT represent "institutional zionist power in the U.S." as it's not a mainstream Jewish organization.
