It's primarily the fault of liberal fascists and their proxies on the Colorado Civil Rights Commission. This sort of bullshit harassment should never get to the Supreme Court. Maybe in a few years the case will return to the Supreme Court where Kavanaugh can assist in providing a less nuanced defense of religious liberty and freedom of speech. That would be a, ahem, delicious irony.
But I suspect some fascist will simply torch this poor guy's shop long before that happens.
