Firstly there are other people who want to discuss the issues already raised in the GD thread. On that ground alone Brian was absolutely right to raise this post. I suspect that your objection is based more on the fact that you are doing very badly in the GD thread - which is entirely your fault -
As for your empiricial evidence I very much doubt that you have anything new to bring to the table so why should Brian wait for that ? It's just going to be the same old rubbish that has been thoroughly dealt with in past threads. There's probably no good reason to even talk about it in the GD thread.
I'd also suggest that instead of wasting time with Ellis' rubbish - which is throughly incompatible with Wyatt's rubbish and with the Bible - you could have got on with more productive lines of debate. If you choose to tie yourself up in knots instead of making productive contributions that is your problem - and not one that you can blame on anyone else.
