Libs and reactionaries will continue to use the implication of anti-semitism as a weapon against the left as it is one area they think they can show as the left being hypocritical (unfortunately there are some blurred lines and issues with actual anti-semites, though still a lot less than in chud or lib circles) . When Jewish people like yourself stand up against that narrative it makes their criticisms less effective so they will do everything they can to discredit you. They are happy to be anti-semitic and insult you and anyone else standing against their narrative as long as it lets them get a jab in at the left and it sucks that they have been allowed to get away with this.

Try not take any of it to heart, fuck those people, they don't get to decide who is and isn't a good Jewish person just because they like one particular side of the community.
