Issue with your first premise about Socialism... I have never heard leftist and Socialist circles take specific issue with Jewish people. Quite frankly the stereotype of the rich Jewish person is tied into the idea of Usury being a sin in Christianity but not the Jewish faith... But when was the last time you heard of the church full of fire and brimstone proclaim participating in the stock market is a sin? Answer is, you don't. Because it doesn't happen anymore. As dogma goes it was subtly retired from popular consciousness over a lengthy process about 300 years ago. The concept of "the Rich Jew" being a distinct issue for having any kind of advantage over anybody else is just the lingering unexamined myth of an era where any loan made where interest was charged had limited sources. There is no bogeyman money lender anymore when secular short term loan businesses dot the landscape.

The factor the main branches of Socialism all agree on is that the super rich should be taxed and measures made to put checks on monopolies. The faith of the people in those positions has zero relevance to that discussion. The common denominator is the amount of money made and the social ills that are perpetuated when that wealth is allowed to be unambiguously hoarded. Assuming that targeting the rich unfairly targets the Jewish people is buying into the antisemitic stereotype that paints them as the only rich predatory bogeymen of consequence.

What Conservatives often don't realize about hate speech is that there are protected and unprotected grounds. Israel is a political construct, a country. Becoming mega rich through exploitation is a choice anyone can make. Neither of these things are beyond criticism because they are both institutions independant of the body of religion. You have Jewish people who hate what the body politic of Israel is doing and you have rich exploitative people who are not Jewish.

The near complete lack of understanding of the actual hard boundries of what counts as hate speech versus legitimate targets of criticism leave a lot of moderates in your position where they are out to sea and unable to pick hate speech properly out of the dialogue and are subject to false equivency propaganda that there's hypocrisy when there's not. In rhetoric there are solid rules about what counts and until you learn them you are sailing without a compass or stars.
