The thought occurs to me that one interesting way to help get past this might be to compile sets of posts on the relevant topic(s), posts which cover all the basic issues as well as many of the most salient objections, and have it indexed via a table of contents, keywords, etc.
That way, rather than saying "Yeah, yeah, we've already discussed this before" one could say "Not only have we discussed this before, this very point has already been specified. Check out the Qualia canon, in the section on Turing computation, and you can read the objections to your claims. We'll respect you a lot more when you can contribute something new to the canon."
