For the reader unfamiliar with the situation, the block was set in response to my repeated use of the phrase "deletionist vandals" on several AfD entries; according to karmafist, I was being an asshole to deletionists (who do indeed disagree with me) by calling them "vandals".

Now, karmafist, you and I both know that there are people who think it is acceptable to replace the contents of Snoopy with, say, "Snoopy is a shitfaced cockmaster."  I disagree with those people, and I'm sure you do, too.  In fact, there are lots of people who doand they refer to the aforementioned individuals as "vandals".  However, they are never blocked for this.  Since, according to you, "being an asshole to people who disagree with you" is a blockable offense, it follows that one of the following must be true:
Calling someone a "vandal" does not constitute being an asshole, in which case I should not have been blocked because by calling deletionists (who disagree with me) "vandals", I was not being an asshole to people who disagree with me.
Your statement that it is unacceptable to be an asshole to people who disagree with me is false, in which case I should not have been blocked because assholery is in fact not unacceptable behavior.

Or perhaps you meant to say that because someone disagrees with you is not ipso facto sufficient reason to be an asshole to him.  Again, one of the following must be true:
Calling someone a "vandal" does constitute assholery, in which case one can infer (from the fact that those who refer to the Snoopy types as "vandals" have never been blocked for that) that it is acceptable to engage in this specific type of assholery towards those who are indeed vandalsand, as I proved on User talk:Aaron Brenneman, deletionists are indeed vandals (you claimed that my proof was "bullshit" and that it did not need refutation, but your assertion does not make it so)
Calling someone a "vandal" does NOT constitute assholery, in which case it's all irrelevant since, as I was not being an asshole, the conditions under which being an asshole is acceptable are not an issue.
Calling someone a "vandal" only constitutes assholery if it is false, in which case see the above-mentioned proof as to why that is not the case here.

Now, which of these alternatives is it?  Alternately, you can show me a fallacy (if I were you, I would try and find a false dichotomyor trichotomy, for that matteras my argument rests on showing you how none of the possible conclusions of your argument justify a block on me; perhaps you will be able to find an alternative I have missed that does indeed justify blocking me) or a mistaken premise and I will gladly concede that my behavior was wrong and was deserving of a block, and will change in the future.
