Agreed, good points. You should send your rebuttle to the publication that printed the article in the first place.
Fact of the matter is, certain bars and clubs have pat downs because of past problems with..ehm.. certain members of society trying to bring in illegally concealed and illegally owned weapons.
If barowners don't want weapons inside of their bar, post the sign. It's really not a big deal. The baddies will still take theirs in and do what they will, so they'll only be stopping the law abiding members of society, but alas it is the owners right.
