When a lesbian, gay, bisexual, or transgender person supports his, her, or hir own oppression -- his, her, or hir own community's opression -- that to me is just a bit sad and depressing. But, there is the libertarian argument rejects the idea that it's a function of government to involve itself in policing discrimination (emphasis added):

    t's wrong to discriminate against an employee just because he (or she) is gay, but it isn't the government's business to prevent business owners from doing wrong.

B. Daniel Blatt at GayPatriot Would ENDA lead to forced "outing"? argues that the Employment Non-Discrimination Act (ENDA) isn't necessary, and may resort in employers outing their gay and lesbian employees in the workplace.

o.O That makes zero sense to me.
Ofcourse it's the government's job to prevent companies from "doing wrong", that's why there's law protecting citizens and police to enforce it!

As a recently-ex-libertarian, I'm not entirely sure how I feel about this.  Yes, I'd love for people who unjustly discriminate to be punished for it, but... can the state actually do this in a way that's fair to all involved?  No de facto quotas, no "though police"?  Can we be more ethical in how we handle allegations of discrimination?
