Yes, except in jobs where gender identity matters

For example, a gay man shouldn't see boys naked in non-medical environments. And if the behavior they choose, rather than simply the orientation they don't get to choose, interferes with their ability to perform all aspects of their job fully, then they can be discriminated against. For example, an openly and clearly gay man working as a server af a restraunt may make customers feel uncomfortable. In this case it is their behavior, not directly their orientation, that can be discriminated against. I think I should be discriminated against for my religion if I choose to say that my religion means I can proselyte freely to unwilling customers.
