This thread is a very good example of what I very much dislike about the Guest format.
Those I refer to as antagonists can in fact post something like the original post here under the guise/pretense of belief/opinion/preference.

Lurk in wait for some responses and then jump in ridivuling the baiting post.

This thread seems to fit that pattern. Mudslingers setting their own stage.

I fully understand the reasoning behing the anonymity/guest format. It does however leave the door open for deteriorating quality of content.
