The golden rule: "do unto others as you would have them do unto you."  The rule being followed, and explicitly stated although in other words: "Do unto others as you perceive them to have done unto you."  In other words, repay "snark" or perceived "snark" with snark, respond to perceived attacks with attacks.  This after all, is what Jesus taught his followers isn't it? One one must assume that a poster who claims to be a catholic is a follower of Jesus.  So when that poster proclaims that he attacks when attacked, snarks when snarked, that poster is representing Jesus' teachings.  Or is disregarding them because he isn't actually a follower?  Or believes those teachings have been superseded, perhaps by the Rites, Ritual, Regulations and Habits of the Church?  Its all quite confusing, or possibly hilarious, depending on the poster's intentions.
