I misread the tweet, they said "black-rimmed glasses" rather than "sunglasses".
So it seems to boil down to, "It seems like most of our critics are those upwardly-mobile Jews." Another sad chapter in the descent of WikiLeaks from a journalistic organization that was a reason to hope for humanity into a the Daily Mail for the Kremlin instead of GCHQ.
>Regardless, the parentheses are pretty straightforward.
They really aren't, as the tweets hint they've recently been some sort of an anti-anti-semitism symbol, with lots of jewish people on twitter putting them around their names.
