Look at photos from “Up Your Alley” street fair. When I viewed them, I started dry-heaving. Hopefully SF disinfected the streets and walls because of body fluids sprayed about.
There is a blogger, Zombietime, that has the pictures. He/she must have a strong stomach.
My grandmother lived in Oakland back in the 70’s and would take me to SF everytime I visited. SF was always my favorite city, not so much anymore.
I looked at those photos as well. After doing so, I have come to the conclusion that there are segments of our society where mental illness has ravaged the spirit and mind to the point where absolutely nothing is off limits, no matter how perverted or disgusting it may be. These perverts have reverted back to crude animalistic behavior and left whatever shreds of humanity they had behind them.
Science should re-classify these perverts as a new species, completely separate from human beings.
