The problem is, HP didn't dream up this diversity crap on its own. 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.
Homosexuality is neither a religion nor a religious belief. Sodomy is an unnatural act, and as such it is a violation of the natural law upon which all just law is founded. The State, especially one claiming to promote the "general welfare" or the common good, is entirely justified in prohibiting anything that supports homosexual activity. At the very least the State should not be endorsing homosexual activity.
