First of all, as I suspected, @liminal has pointed out that straight people are allowed to participate in the Gay Games.
But even if they were not, the oppressed are socially allowed to exclude the majority. That’s the way it’s historically been. That’s why men’s colleges are seen as discriminatory while women’s colleges are seen as empowering, that’s why my alma mater has a Black Student Union and a GLBTA but certainly does not have a White Student Union or a Straight Students Club. And you know what, I think that’s fair! Those born into privilege don’t need their own clubs and organizations because they aren’t the victims of discrimination.
Is that hypocrisy? Hell no. Victims have rights that the privileged do not and must not have in order to create some semblance of equality in our world. Without these “inequalities” as you see them, the discriminated would be ever further behind those born into privilege.
This is not to say I think the GLBT community needs its own olympic games, I actually think it’s really silly, but if we want to have our own damn olympic games, then you shouldn’t say two words about it. It ain’t your place. Are you barred from marrying the person you love? Is it legal for you to be fired simply based on your sexual orientation? I didn’t think so. So until we’re equals under the law, shut up and give us our damn Gay Games.
