I find it absolutely hilarious that you believe that Comintern - an organization that was dissolved in 1943 - is still "funding and driving" civil rights struggles.
As someone who used to be active in a party that used to be a part of the Comintern, and that spent a lot of time during my youth to try to build support for re-establishing an International, and who learned in the process there are about a dozen "Fourth Internationals" (Comintern was the Third), a few Fifths, and at least a couple of Sixths, none of which acknowledge each other, all of which are ludicrously impotent tiny little groups, the idea of some shadowy remnant of the Third actually still existing and having the power and will to do something good for a change is some world class tin foil hattery.
I also love how you try to pretend that it was a secret that Einstein was left wing, yet at the same time try to push the idea that the supposedly left wing US press (... as a European, the very idea of a left wing US press is comedy gold) were exaggerating his worth as a physicist because of his secret left wing views.
By all means, keep on going. It's exactly this over the top lunacy that have changed US attitudes to socialism - the rate of change the last 20 years have been astounding. Maybe in another 20 your political landscape will start to approach the European.
any one of Einstein's contributions in his miracle year would have put him in the history books. to say his contributions to science have been exaggerated is incorrect. he really was that good, whether you like that fact or not.
