Employers and employees do not usually bargain like that. "I'll stop my obnoxious behavior if you'll change your business practices."
The unconstitutionality I'm referring to are laws/judicial decisions forcing acceptance or normalization of homosexuality such as the law in CA mandating "gay" friendly promotion cirriculum in public schools K-12 since 2001.
If you want to shift the discussion from private workplaces to schools, ok, but that is a totally different arena. So which article of the Constitution is being violated?
"This is either a federal mandate or a preemptive move by HP to avoid a future lawsuit. It all boils down to a federal imprimatur for homosexuality that is going to affect every corporation."
