The headline is slightly misleading. It's a good start. The court opinion looks like it covers all LGB folks.
"... and we conclude today that discrimination on the basis of sexual orientation is a form of sex discrimination." - 7th Federal Appeals Court
Now we need to establish grounds for treating discrimination on gender identity or presentation as a form of sex discrimination. That's a bit of case law still to be done. Then I'll be happy.
LambdaLegal did a great job in pushing this through the full panel, though. Big task, and well done!
