The fact that Trump has many influential Jews in his administration does not prove that he’s not an anti-Semite.
However, the fact that he’s not an anti-Semite does prove that he’s not an anti-Semite. (Has anybody caught him saying anything anti-Semitic?)
That being said:
Trump is clearly not an anti-Semite. Not only that, but he has clearly denounced all of the various anti-Semites that (quite enthusiastically) support him.
However, the launching of Trump’s Nationalist-Populist movement has both energized and popularized the “White Nationalism” movement of the “Alt-Right”, which is essentially just a repackaging of the ideology of the KKK and the Nazis. This “White Nationalism” has gone from being a fringe, marginalized movement to being a visible force with an increasing amount of adherents and influence. This is, to put it mildly, not something that we should be excited about…
