"All others"???
I linked to 3 sources above that clearly show people playing it as negative. Bridge world std, based on poll of readership which tends towards advanced/expert. The 1nt battlefield site. The ecats site that has downloadable convention cards of all the recent world championship participating pairs, if you look through I'm sure most play negative.
You like Bergen... Maybe you can take a look at Bergen's partner when he was still competing, Larry Cohen

Something like 20:5 in favor of non-penalty
It makes sense you haven't played live tournament bridge since the 70s. Bridge bidding hasn't remain frozen in time in the interim. Don't think you know everything and can convince anyone when you give no logical arguments whatsoever other than declare things to be a certain way on your authority. You are getting no support here because very little of what you state makes any sense to anyone other than yourself.
