I think you already know my perspective. The right to discriminate is a human right. Discrimination is usually perfectly harmless anyway, as it was in the case of the baker. This woman was targeted for her religious beliefs. I do not share her beliefs but I do recognise her right to hold them.
If you want to remove the right to discriminate then you must close down all women’s groups, all black groups or gay groups or anything else that excludes anyone at all.
On top of that I think it is an affront to the principle of individual liberty for any government to interfere with the practises of any citizen unless that citizen was infringing on the rights of someone else. The baker was not infringing upon the rights of anyone else. She was not doing anything that was going to hurt anyone other than maybe her own business.
