Could you expand on this a bit? I'm genuinely asking. The article sums up the contention pretty well:
> The legal fight focused on the definition of “sex” in Title VII. The plaintiffs, along with civil rights groups and many large companies, had argued that discriminating against gay and transgender workers was inherently based on their sex and consequently was illegal.
At first glance, I think I agree with Judge Lynch. Its great that these protections extend to more people, but I think the argument is tenuous. A gay man and a straight man have the same sex, so discrimination against the gay man is not really based on sex, but on sexual orientation.
And, as I understand it, the difference between sex and gender is very important to transgender people. Biological sex != the gender you identify as, that's why we say trans_gender_ and not trans_sex_ . How does a MTF trans person who has not undergone surgery / hormone treatment / sex change answer if asked what her sex is? Again, genuine question.
I guess this is a "spirit of the law" situation, where "sex" doesn't just mean "sex", but all sex /gender/orientation/ groupings of people.
Personally, I think it would have been ideal to amend the law and explicitly add gay / transgender people as a protected class. This avoids the possibility of another case in a few years overturning this one. But the current congress would never write such a law.
