Elegran. I agree with your first post.
This is a thread about a thread about a thread about a thread. Another thread asked did we need all these threads prior to this one. 
The wording of the OP, like a lot of OP's on other threads ,has an irony to it as the majority of us will view it's content naturally from our own perspective. That is precisely why and how we 'debate', if we didn't then it would merely be a posters 'statement' and what would be the point of joining in. After all the posts on all threads 'do invite others to reply', unless making a statement was the intention all along.
However it has got 'shrill', 'nasty' whatever you want to call it on a couple of threads. I have seen worse before and whilst it can become distasteful it is good to be able to see, consider and make a conclusion based on what we read for ourselves about each poster and how the issues arise. I would hate for GN to delete posts for that reason but I feel it is getting a bit close to call.
