Criticism of AIPAC is not criticism of Jews. Period.
It is a criticism of Israel, but there are many Jews both in Israel and the US who do not agree with the Likudnik right-wing government that has held Israel in its grip for so many years.
I appreciate your personal experience as a Jew, but I would urge you to read this personal account from Ady Barkan, an actual AIPAC lobbyist:
From the article:
As a Jew, an Israeli citizen, and a professional lobbyist (ahem, activist), I speak from personal experience when I say that AIPAC is tremendously effective, and the lubricant that makes its operation hum is dollar, dollar bills.
AIPAC is a political organization whose purpose is to promote the interests of Israel in the USA. That seems simple enough, right? But defending AIPAC assumes that the geopolitical, economic and strategic interests of the USA are 100% aligned with those of Israel. That is not the case.
