Unfortunately Americans are just as capable of idiocy as Russian trolls, so it's hard to sort them out, but when my spidey senses go off (poor grammar, off-beat message, odd choice of picture, etc.), then I pop the Russian roomba.

i read a fb post this morning that misrepresented a bunch of false facts so eloquently, it was hard to believe the person was just dumb. i always leave open the possibility that posts here or there are calculated to manipulate the simple-minded.
