Whataboutism. Clean up your own act before you throw stones.
Cool guys like Abdulrahman are infiltrating the Dems and dragging it left. Abdulrahman would never fund Israel. But you talk like he doesn't exist, you reduce the entire party down to the cynical old timers in the ologarchs' pockets. While ignoring those cynics' very aim: to lose.
You and the DNC are walking hand in hand towards the same goal, using the same methods. You're both trying to keep idealists like Abdulrahman from making change, by ensuring he loses to the fascists.
