From the Human Rights Campaign, a list of businesses rated according to their support of equal rights for lesbian, gay, bisexual and transgender people. They also deal to some degree with racism and other sorts of intolerance. Which to me is absolutely necessary. Some "human rights" organizations get myopically focussed on one group of people, but human rights is about ALL people.

Here is HRC's info on which businesses are most tolerant with regard to variation in sexuality and gender identity. I thank them for their research. I would like to see this info cross referenced with an environmentalist/non-consumer perspective and see how many are left in the "green" category.
