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 <i>unfiltered</i> commentary is <i>on your own page</i>, or <i>in a letter</i>, not <i>in comments on someone else's page</i>. Doesn't matter if they're a public official; comment pages need moderation.<p>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.<p>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.
