Yeah, realistically anyone who is creating websites for a living shouldn't give a fuck about who they are creating it for. The KKK is a terrible example because that is 1. a hate group and 2. a group you join on your own volition. A business could take the same stance against anyone wearing BLM apparel, as that is a group you join on your own volition. Being a certain race or sexuality is not something you join on your own volition, you are a member of that category because of a trait you inherently have not because you decided to join a group.
