Was it just me or were people scared to death of the street people?
I have an MSW from PSU and worked in a medical clinic for homeless folks for 7 years. I was an activist for homeless rights for years. I've lived houseless (e.g., in a tent at the Buddhist Retreat Center last summer). I have had tons of friends who have been homeless, and, notoriously, I even awarded a prize at one (non-Kumoricon) convention to someone, 3rd place in an art contest, who turned out (I found out afterward but did not rescind the prize) to have wandered in, homeless, just to keep warm and safe, and picked up our art supplies and drew and colored a piece.
So I would definitely say I am way more comfortable with homeless people than most.
And yet I must admit. It was a little unnerving, walking up the many, many stairs to the PSU dorm where I was staying, 10 blocks from the hotel, alone, at 4 in the morning, in Luna Lovegood cosplay, with my purse and suitcase, while a street dweller who was swinging (rather than leaning on) a cane was having an angry fight..with himself...
