The problem is there has been a disconnect about this for ages. It's the tipping point beyond the perfectly sensible and reasonable change in society perspectives on tolerance and prejudice.
Which is what usually happens when sensible ideas get filtered through a lowest common denominator lazy culture - we all agree prejudice is wrong and tolerating differences is how human society will function in the most equitable and free manner. It's an admirable goal.
But it takes compassion, intelligence and patience to achieve. We were managing quite well for a very short time, but, as so often happens, it was a lot easier to slip into using totalitarian compulsion and actual scorn which is why we have ridiculous self defeating arguments about 'Not tolerating intolerance' and namecalling instead of 'let's talk about why people view the world that way, how we can address their concerns, and how we can live peaceably if we simply don't ever agree.'
