Federal Court Rules Politicians Can’t Block Constituents on Social Media

While I certainly think it makes sense to be able to criticize and discuss politics and politicians in any medium you have available, the right place for unfiltered commentary is on your own page, or in a letter, not in comments on someone else's page. Doesn't matter if they're a public official; comment pages need moderation.

This is not a good precedent; this means that if someone wants to spew incoherent, hate-filled invective, the basic tools of moderation are unavailable to deal with that.

The right analogy here is not to a letter or demonstration; the right analogy is the peanut gallery at a courtroom or legislative body. If you decide to start screaming in the middle of such a location, you'll be told to shut up or be removed as disruptive. You can take it right outside if you like, or stick it on a giant poster on a stick.
