You're 100% correct. If NYU doesn't expel those Nazi's, then hell should be raised about it.
We Jews need to be on guard and vigilant 100% of the time. If we don't speak up, make a stink and fight back, then we're being very negligent about what the future may bring. When a Mayor of a U.S. city can talk openly and freely about Jews running the country, only a very naïve person wouldn't figure out where this kind of talk may lead. And if students in a major U.S. University can commit anti-Semitic acts like this and get away with it, and if the University treats it as some kind of stunt, then we Jews aren't doing our jobs.
NEVER AGAIN!
