The "alt-left" is out there. I see them as the those who are Left of Hillary and Barack. There are three or four types, but all are white.
There's coffee shop, hang out Dude-Bro, who sips $5 latte. He's the, "We need to end capitalism first!" type Lefty. He is almost always sporting dreads. I see them as the Millennial version of Che Guevara, but without the willingness to take a bullet.
There is also the Lena Dunham, dumbass meme repeating type Left. These are mostly females who think they are edgy but are really just superficial, shallow and lame. You'll see them often with matted hair they think of as dreads. They too hang out at the coffee shop sipping latte. Most of them flock toward Dude bro, especially if he plays an instrument.
Then there is also the hipster Left. These folks are a lot like Dude Bros and Lena Dunhams, but they pay more attention to fashion. The womyns tend to wear their hair long and straight, and on their face is usually a pair of old fashioned frame glasses. The dudes have girlish figures and wear skinny jeans, plus those same frame glasses.
And, lastly, we have the aging hippie left. These are the people reliving the Vietnam war protests at every opportunity. Many of them are retired professors and school teachers.
