That was my point. It is not "unsubstantiated rubbish", it is a fact. There is not J2.

Imagine coming to a forum discussing the Bigfoot or alien abductions and posting something like, "there is no Bigfoot, get over it." Sure it would ruffle up some feathers but until you can prove it was a deliberate provocation, you must assume it was meant to introduce some reason into the discussion. And it would be the Bigfoot believers to prove the post wrong rather than calling it "unsubstantiated rubbish".
