benignuman, there are exceptions, such as during WW II, when Rabbanim did march to Washington. For something as terrible as mishkav zachar, I’m not so sure the quiet approach is the correct one. Either way, there are Jewish politicians, as Health noted, and other ways to properly and appropriately express our absolute disagreement.
JayMatt, Regarding, my point 1, I apologize for omitting the other two. But the point still remains. Rashi even writes that despite such behavior, they still respect the mitzva to the extent that they don’t write a kesuba. Whereas today, they’re essentially claiming there is no such mitzva. This is obviously not a smart idea.
As to my points 2 and 3, they are not paradoxical at all. Oy LaRasha has implications for others, as I wrote. There is plenty to look up in Parshas Korach and elsewhere on this matter. But outside whatever that association is, the gentiles are responsible for their own behavior; there is no arvus to them as there is between Jews.
