Of course. But also, of course, two wrongs don't make a right.
Correct. If it's ever proven that Russia covertly and significantly interfered in U.S. elections, it should be condemned for doing so.
But for U.S. Democrats and other wannabe progressives to stridently condemn Russian interference, while studiously ignoring/whitewashing their own country's (and their own party's) decades of identical crimes, only taken to an exponential power, and ongoing to this day? That's nothing short of obscene. And the underlying notion that AMERICA could never elect a neo-fascist buffoon like Trump without some foreigners subverting AMERICAN DEMOCRACY™? That's crossing the border into tragi-comic self-righteousness.
A lot of progressives do do that. Many don't. Having elected Nixon, Reagan and W., no one's under any illusion that "it can't happen here." But that's a separate question from whether the election was corrupted by outside intervention.
