Yes. But I see it as fringe voices being given the cloak of mass protest, when it doesn't actually exist.
It's fabricated rage. James Gunn, for example, was fired from a movie series that he created because some hardline conservatives purposefully hunted for copies of his old deleted tweets. That's a terrible precedent to set.
Roseanne immediately apologized for writing something stupid, and she continues to regret the joke to this day. That's remorse. What more can you ask of someone?
The show will collapse without her, and the hundreds of people working on it will be without a job... all because of a Tweet... something that is utterly meaningless.
I'd like to meet the people who are actually affected by these tweets; the people who are actually hurt by reading bad jokes on the world wide web.
I don't know if anyone actually had their feelings hurt by any of these tweets; I'd like to meet them too, if any of them actually exist.
I think what it comes down to is that, if someone makes a slip of the tongue, the general feeling is that it reveals something about their inner character which is viewed as something ugly in contrast to their public image. Even if they apologize, the milk is already spilled. The idea is that if someone has such ugly thoughts in their brain, then they must truly be irredeemable. They're considered horrible human beings, or "deplorable," as some might put it. No apology will cut it; there is no redemption, no forgiveness, no reconciliation.
However, in the example you cited regarding James Gunn, it seems that everyone has skeletons in their closet. Everyone is a little bit "deplorable" in their own way.
In a culture where grudges are permanent and there is no forgiveness/redemption for being politically incorrect, it's not that difficult to see why civility has broken down and positions have become more polarized. When one side sees itself as morally superior to the other, then the other side will try to challenge and tear down that perception.
And that may be where the solution to the problem lies. The kind of self-righteous, supercilious, pompous, arrogant, overzealous "moral outrage" which dominates political discourse should be attacked for its own sake.
