The first cure is to ban private censorship. Make the First Amendment apply to individuals. Somebody poses with a Confederate flag, or even posts on Stormfront? Unless the person specifically does something to identify as your employee or as affiliated with you, you can’t touch him.
As for blogs, define them as public accommodations, subject to Civil Rights laws. If you ban someone, they get due process. You respond to their challenges in a timely manner, and they get to confront the witnesses against them. That means they get to know who flagged them, and get to apply sanctions if the ban is found to be without merit.
My own blogs make it simple. No comments. Because I don’t give a rat’s patoot what you think.
I retired from a university that was founded to be extremely “innovative,” meaning if any carbon-based life form in the galaxy had ever done it, we couldn’t, because that wouldn’t be “innovative.” One of our buzzwords way back then was we were preparing our students to be “agents of social change.” Well, gee, why are we surprised that people on the receiving end of that “social change” might be a bit hostile?
Oh, consider this:
We don’t need no education
We don’t need no thought control
No dark sarcasm in the classroom
Teachers leave them kids alone…
Conservatives didn’t write those lyrics (Pink Floyd, “The Wall”). If you want more liberal anti-intellectualism, look at the people opposing telescopes on Mauna Kea, or read up on the near-loss of “Kennewick Man.”
