How many people posting here have a gay friend? Do you have to have one to think that gay people should not be discriminated against?
That's true. But it's hard to fully understand the discrimination that went on if you didn't have gay friends. I don't think the full scale of the problem is really apparent if you don't have some insight into what is happening.
I was talking to someone in work - a very senior banking professional in the US. To hear her explain how there is a constant concern every time her son goes out as to whether he'll return or not is mind blowing. This wouldn't be "inner city low income" areas - all black people in the US have to be taught how to handle and diffuse confrontation with police irrespective of background or activity
