How to handle bigots as a canvasser?

So I currently have a job as a street canvasser for a gay rights organization. That basically means I stand on the street with a binder asking people if they have a minute for gay rights and trying to get them to donate to the organization.

Naturally, my line of work attracts a lot of bigots, even though I live in a liberal city. It’s emotionally really difficult to cope with. The other day somebody told me to, and I quote, “go die of AIDS.”

What’s a queer chick to do? I love this job, but I’m only 18 and this is kind of a lot to cope with.
