I don't think the first click here really supports the point you are making, however the second clearly did deteriorate. This is nothing new, there have always been heated debates. If they get too heated the FE puts a stop to it. Once, a long time ago, I asked the FE, via email, to stop a thread I had started because it was rapidly going downhill and he took the rare step of doing so. He will not normally stop a thread until he himself decides the time is right.
