There are a lot more Christians than there are gays, yet you don't see Telluride going out of its way to Block out and sponsor a Christian Week. Why do you suppose that is?
From a marketing point of view, Christians, as a group, are not distinct enough to be targetted. How do you put together a marketing plan that will attract both evangelicals and Catholics, for example?
Homosexuals, on the other hand, are much more easily targetted by marketing. Plus, based on their average level of education, disposable income etc., they're a pretty attractive group from a marketting perspective.
