One thing I learned on that story: Sarah Sanders was not the one who broke the news about her eviction from the restaurant. An employee of the restaurant did, on his Facebook account.
If you are someone who believes that Masterpiece Cakeshop ought to have been forced to bake a cake decorated for a gay wedding, but you think that Stephanie Wilkinson was right to kick Sarah Sanders out of her restaurant because she hates Sanders’s politics, then you are an unprincipled hypocrite.
I believe that Masterpiece Cakeshop has that moral right, and I believe that the Red Hen has that right too. Whether they have that legal right is a different question, and whether they should act on that moral right is another. But there’s an important distinction here.
