You don't understand; this is the world of a post-Trump election. The left is now beating the drum in support of all kinds of issues they used to oppose: censorship; stripping internet anonymity; gun ownership; violent revolution; succession. Their surveillance state that they loved and supported under Obama, they're now demanding he tear down in his final months lest Trump become its master. The office of the unaccountable god-emperor President, beloved by the American left just 13 days ago, is now their greatest fear.
Simply put, the tantrum response to the election will continue, regardless of previous beliefs, regardless of well-understood reasons for why some things are the way they are, and especially regardless of any Supreme Court ruling. It's all gone upside-down and you should expect to see the left continue to attack free speech. What began years ago as "political correctness" and accelerated more recently into "micro-aggression" and "safe-spaces," has now turned on the afterburner and is proceeding a mach speed into naked censorship.
Free speech was a vital tool for the left 50 years ago when they were the minority. When they became the majority it was no longer necessary. Now that they're a retreating and threatened majority, it's a danger to them.
