It seems wrong (and not a little racist) to convict a person based solely on their ethnicity without knowing what they actually believe. Jews are very diverse in their opinions, including on issues surrounding Israel and Palestinians. For some, Judaism is a guiding principle, for others it's merely a cultural identity. 

Schatz identifies as Jewish, but that doesn't therefore mean he has any hostility toward Muslims, nor does it necessarily determine his positions. He supports the Iran nuclear deal (which Netanyahu vigorously does not). He supports a pathway for citizenship for illegal immigrants. He has cosponsored resolutions with Keith Ellison (whether he supports him as party leader, I don't know). Point being ... I think I made my point.
