John it's only common knowledge in your head.  You've pasted this stuff around so many sites you actually believe.

Part of the problem is that you're not open to anything other than your opinion, or the opinion of people whose writing you've boosted from other places.   You re-paste long passages from other efforts of yours, not realizing whose writing and thinking it was in the first place.    I've shown this fairly recently.  It's hard to keep track of of provenance when so much of your writing came from other people.
