A quick word on the matter: there is no possible situation under which calling another editor a liar is remotely acceptable.  Accuracy of statements can be disputed, certainly, but "liar" means someone who makes intentionally false statements or willfully deceives.  Given that it posits malice (which is the opposite of assuming good faith), it cannot be anything but a personal attack.I make no comment on whether a block was an appropriate response, or whether its duration is adequate, but arguing that it was not a violation of NPA is ridiculous on its face.  I'll grant that no warning was given, but I am under no delusion that Giano is not aware of the meaning of the terms he uses, or that he has somehow forgotten our policies.  —  (talk)
