Has anyone else posting in this new system had the experience I have had?

That is: You post a reasonable and polite post, and a couple of other people start having an infantile name-throwing argument UNDER your post that has nothing to do with your own material...

... and VOILA, the system reacts by deleting YOUR original post, the whole thread?

What is up with that? 

Some kind of stupid robot system that automatically handles flagged posts without determining where the troublesome content is coming from? Is that what we face?
