Repeat after me: I am not entitled to force other people to do something for me for my own comfort or happiness.
No you do not have a right to have that bakery make your cake
No you do not have a right to be spoken to in a cordial or polite manner
No you do not have a right to any business’ services unless that business is supported by your government.
It would be nice if bakeries would just bake a cake for whoever wanted one, and everyone was polite and cordial and businesses were just happy to serve everyone universally. Something being “nice” and something being necessary for the government to force its citizens to participate in are two majorly, incomparably different things. Jesus.
