I'm not really in favor of special protected classes for anyone. Businesses should be able to hire whomever they wish to representthrm and work for them if they pass on qualified candidates because of their sexuality, or race, or whatever, then that loss is the burden of that business as the person in question goes on to make successes for a rival company. Forcing a social choice down the public throat is just begging for more unpleasantness to find its way back up. Don't stir up the radicals at either ends of the scales, just quietly act within your own ethical behavior to treat everyone fairly. You don't have to condone a life choice to still do that.
