In my opinion, it's not about the act of discrimination itself, but the method used to combat it. As an extreme example, I think everyone agrees that littering is bad. But how would you feel about summary execution for littering? Feels crazy extreme, right? The actual effective punishment for littering is more like people maybe frown at you a little, and maybe if you're super obnoxious about it or do it right in front of a cop, you might get a modest fine. That seems about right to me. I feel like I'm complaining that maybe we shouldn't summarily execute people for littering and everyone's coming back at me with how dare you support the evils of littering. I don't like any kind of discrimination. If everyone in town is discriminating against some group so hard that they can't go about the ordinary activities of life, that feels like something that needs to be addressed by government action. On the other hand, if one business in a medium-size city doesn't want to serve some group for some reason, and there's a dozen competitors that are fine with that group, maybe it's best to just let it slide from a legal standpoint. Maybe a local soft boycott or something like that. If you want to ratchet up the severity of the punishment for an act that is vanishingly rare and hasn't really caused anyone that much trouble, consider the possibility that you aren't the good guys anymore.
