The distinctions between anti-Semitism & anti-Zionism are not subtle. Claiming evil Zionists are behind every single social problem on the planet is a not very well disguised form of anti-Semitism which does not strengthen Palestinian political power one iota but, on the contrary, undermines it. Zionist influence in politics is far-reaching. They play a role in war mongering, anti-immigration programs, eugenics & forced sterilization programs. But it is not clear whether they operate in rightwing politics as a function of their Zionism or if Zionism is on a continuum with their rightwing approach to all politics. That distinction matters. It isn’t useful to demonize them because that clouds judgement & really is a slippery slope to anti-Semitism.
