Never thought I'd wind up posting in this thread, but my dad apparently had the wildest encounter with an SJW the other day.
For some background, my dad has a Donald Trump bumper sticker on the back of his car, and he was on the interstate trying to drive home from work. Suddenly, this guy starts driving up behind him really fast, but slows down just short of rear-ending him, and he does this repeatedly like he's just charging at him. My dad tried to move lanes so he could get hopefully get out of this guy's way, but the guy sped up and cut around him, nearly clipping his bumper, and stopped in front of him.
The guy then proceeded to get out of his car, walk over to my dad's car and started banging on his window, screaming at him about how horrible he is for supporting Trump. (He doesn't remember the specifics because he sure as hell wasn't going to roll down his window to hear this guy better) Again, this is in the middle of the interstate. There was so much traffic around him that he couldn't leave, so he just had to sit there and wait. The guy either got tired or realized he was holding up traffic, but he finally left. My dad later just took down the bumper sticker so he wouldn't have to deal with that kind of shit again.
