A fashion designer whose name is irrelevant has stated she will not work with the new First Lady. I haven't heard the official Trump response but I'm guessing it is, "Nobody asked you."
This person also has asked other designers to boycott the Trumps. This is perfectly within her right to associate and work with whomever she chooses. Alas, Progressives do not grant the right of free association to everyone, only those on the "correct" side. A Christian bakery in Oregon was driven out of business and hit with a $135,000 fine by state Labor Commissioner Brad Avakian because the owners refused to violate their religious beliefs. In a case of "Payback is a Bitch," Avakian's activist agenda was rejected by Oregon voters this month when he ran for secretary of state. His opponent became the first Republican to win statewide office since 2002.
Sometimes rights conflict, but reasonable people can work it out. Or you can have a tinpot dictator trampling on his enemies and helping his friends.
