There is a very interesting, but not widely reported fact about one of the young men who organized the protest: he is a second generation (at least) Red Diaper Baby.
His Mother, whom I know and is actually a decent enough sort politics aside, grew up as a Red Diaper Baby in New York City (Greenwich Village) in the '50s and was heavily involved in the New Left in the US (though apparently without much of a public profile). She also spent several years in Germany in the late '60s - early '70s involved with a significant member of the Red Army Faction. Now, of course, she's a left-Democrat.
It never ceases to amaze me how, when you look into the background of those who are leaders of the left and the 'Democrats', so many of them turn out to have significant Communist or socialist ties.
