I agree with Ed (the author of the article) ... no politician should expect "safe spaces" that shield them from public expressions by ordinary, everyday people ... and to Pence's credit, he told his daughter that the scattered "boos" were "what freedom sounds like." So, Pence acted like the rational adult that he is, while the whiny two-year-olds on stage acted like ... well ... the infantile brats that they are.
Ed is also correct in accurately pointing out that what really makes the outburst from the Hamilton cast so demonstrably infantile is that Pence (and Trump) have not even taken office yet - so far, all they have done is win the election. Leftists are such whiny lil' babies that they can't wait to see what Trump and Pence actually do - no, they have to be irrationally intolerant and obsessively complain about their very existence.
