This kind of bad-faith civil engagement that poses as grass roots is a bigger threat to progress than misguided opposition. At least you have a hope to convince or guide honest opposition. Groups like AIPAC are unswayable. They exist solely to enable and advance Israeli agenda w.r.t Palestine. The morality or validity of the agenda just doesn't matter. The IDF could commit its biggest crimes yet and the AIPAC lobby is unlikely to lose funding or human resources. Compare that to other groups, like the NRA for instance. The NRA is cracking at its foundation. Who wants to work for them in this climate? Who wants to take their money?
And they are succeeding and can't be stopped because American Jews are a strong part of the political establishment and have strong family and business ties with many other non-Jewish American elites. They whether whole heartedly or due to tribalism support AIPAC unconditionally and it's not going anywhere. And also you are not allowed to point out this fact for being labelled anti-Semitic but as far as I can tell it's more or less true.
