Because I desperately needed a "Shut up" icon.
Also because eiviiaru on Journalfen asked for this one, and because god almighty, is it needed. If I hear one more person whining that their free speech is being abused because someone responded to their free speech with...more free speech, which just happened to involve telling them exactly why they're an idiot, I'll... er. Rant about it using this icon, I suppose.
ETA: shareable, if anyone wants it.
