It's not a red herring at all. Even given the current law, we still should not make things worse. Discrimination is wrong mostly because it hurts certain groups of people, not because it makes them unequal.
It seems what you really want to discuss is: what would you think if you thought abortion was moral? If abortion was completely neutral, then I'd agree with you. But that condition has everything to do with my beliefs, and nothing to do with current law.
