Diversity friendly workplaces and events

Let me tell you a story early in my career. I was a junior programmer at a large Australian accounting software company. They were announcing that day that the company needed to downsize some of the developer teams. A number of team members gathered near my desk to discuss how "one of them" was let go from the company. Turns out the employee they were discussing was gay and they were discussing how much more comfortable they were without that employee at the company.
