I'm going to be harshere still No we should not remove it. Stenger doesn't have to give a source. TG continually confuses what editors have to do with what authors of source material have do do. As for making stuff up, see Psychological_projection.  What we can see from the recent discussion on SU(5) is not that Stenger was wrong, but that either TG is a pathological liar or utterly incapable of reading technical material. Usually, I apply Hanlon's Razor to these kinds of dilemmas, but your track record here it too long and extensively documented to opt for the stupidity explanation for your actions. Barr is absolutely the first paper to describe Flipped SU(5), derived from SU(5),and his 1982 paper is repeatedly referenced for it, as anyone would discover from even the most casual of Google searches.   Similarly, Stenger was absolutely correct about Derendinger's 1984 paper.  And, I've read the papers, and your statements about them are, to put it most charitably, grossly misleading at best, and less charitably, absolute falsehoods. There is nothing that I can think of that is more disruptive to, or destructive of, the aims of Wiki than the willingness of an editor like yourself to assert blatant falsehoods to try to push your POV on these articles. And yet you persist month after month, year after year, in the most outrageous falshoods, many of which were documented on COIN long before Will or I ever set eyes on this article, apparently with the motive of protecting this article that you wrote and had another editor post at Wiki. It is utterly unacceptable behavior, and frankly inexplicable since your claims are so easily falsified by any neutral editor. This has got to come to an end.  Now.
