What's surprising is how truly upset and angry AT ME some people became over a simple theory, as if I posted it for some evil underlying purpose. I just thought it was interesting is all. C'est la vie...
I think most who know you and are interested in discussion instead of confrontational combat might cut you some slack by recognizing that there will usually be exceptions to most statements of fact.
I think most who don't know you or the author of the piece and are interested in discussion instead of confrontational combat would do the same. Or they might add their own observation that there would be exceptions of course, but the rule is generally a good one or not.
And some will assume that they are being dissed by the theory being presented at all, and they will attack the messenger be it you or the author of the piece.
Right or wrong or something in between, the author at least obviously struck some chords, hit some nerves, or simply peaked some interest among the group.
