Zionism is as much “Jews” as Nazism was blue-eyed blonde people: they’re both very similar ethno-Fascist extremely-racist ideologies which glue themselves to an ethnic group claiming to represent them even while plenty of members of that ethnic group very overtly say “They do not represent me”.
Never believe Fascists when they claim to represent a nation (in the case of the traditional Fascists) or a race (in the case of the ethno-Fascists). In fact, the more general rules is “Never believe Fascists”.
If one thinks a lot, likes to learn and, maybe more important, thinks about knowledge and learning things, that person will probably get there.
A certain educational background probably helps but is neither required nor sufficient, IMHO.
