This gets us to why I think the ruling's majority essentially agreed with the protesters. If I like to dress up as a character from "Game of Thrones" on weekends, pretending to fight snow zombies and treating my mutt like it's a mystical direwolf, that's none of my employer's business. But if I ask my employer to pay for my trip to a "Game of Thrones" fan convention, I am asking him to make it his business. If my employer refuses, that may or may not be unfair, but it's his right. If, in response, I go to the convention and have the government force my employer to pay for my travel, that only makes things worse. It not only makes my private pursuits my boss' business, it makes them the business of taxpayers and a bunch of bureaucrats in Washington.
