Today, American students are forming chains to keep recognizable Jews off campus. This is very reminiscent of 1938 Germany, where activist chains kept Jews from going to university.
Show me evidence of one case of protesters "forming chains" aimed at Jewish students - the protesters, by the way, largely ARE Jewish students. They HAVE sometimes locked buildings preventing anyone from entering, not only Jewish people, in a pretty standard protest tactic. Your comparison to Nazi actions is typically dishonest and disgusting of genocide supporters.
So-called “pro Palestine" activists have been assaulting Jews on the streets
No one is defending actual assault; there have also been lies about assault, and assaults by 'both sides'.
and tearing down pictures of innocent hostages held in gaza, including infants.
Yes, both sides have attacked messaging from the other. Such signs are likely seen as propaganda trying to care only about their hostages and to cover up the atrocities committed against Gaza, and from the far more PALESTINIAN hostages, perversely by the side that is preventing the release of the hostages, with Netanyahu wanting war, and actually killing hostages, not very concerned with them.
You can criticize the 'property crime' of tearing down the propaganda, but it pales to the crimes of violence being protested. It's analogous to tearing down swastikas in Nazi Germany to protest their crimes.
Jewish businesses are targeted.
Define 'targeted' and show evidence. No one is defending crimes against businesses. You do realize most American Jews side with the protesters and are leaders of the protests? And that there have been cases of pro-Israel (Worse than Hamas) people who do things like paint swastikas to create false claims of victimiization?
Synagogues are being attacked, and Jewish graves desecrated. Just 5 years ago, my late aunt's neighborhood synagogue was attacked, and the fanatical anti-semite murdered 11 people for the crime of being Jewish.
Sounds like ACTUAL anti-Semitism - right-wing actual anti-Semitism is not the same thing as the pro-Palestinian protests.
Immediately upon the October 7th atrocities in Israel, mobs of pro Hamas sympathizers, including college students and professors, gathered to celebrate.
Immediately upon the liberation of the Nazi death camps, there were numerous cases of freed prisoners chasing down and murdering fleeing guards in cold blood. Victims of great oppression can have that reaction. I understand genocide supporters would like to try to lie that the entire story began October 7 and is all about the crimes by Hamas.
I also note you did not answer the question, and of course don't have a word to say about the crimes against Palestinians before and after October 7. You simply support them.
