Another response: your argument style reminds me a little bit of a straw man:

  > A straw man (or strawman) is a form of argument
  > and an informal fallacy based on giving the 
  > impression of refuting an opponent's argument, 
  > while actually refuting an argument that was not
  > presented by that opponent. - Wikipedia

... with the twist: instead of engaging with anything I said, you mischaracterize it and large parts of the preceding discussion. Then you use that as a way to dismiss what I wrote as "off topic".

I'm going to have some fun looking up what others call that kind of rhetoric.
