If I owned a store I darn sure would not want anyone telling me what to say or when to say it.
Gotta remember... if Trump is president, and he makes people say Merry Christmas... then the next president also has that right.
No president, no government, nobody has the right to tell any American citizen what to say.
Just don't say the N word....or gays are predators....or ho.......but wmf is no problem.
