OK... I'll bite...
To say a Lab shouldn't point is no different then saying a german shorthair or a brittany shouldn't retrieve.
If you study those breeds, you will find that they were originally shunned in this country because they were not "pure pointers" like the true english pointers. Now, only after many years, it is accepted that both of those breeds are versatile dogs that both point and often (but not always) retrieve instinctively.
If you study the labrador breed enough, you will eventually find that when the St John's dogs were taken to England from Newfoundland, they were bred with pointers in an attempt to create an improved upland bird dog, which is where the pointing instinct comes from in american labs today. It is much stronger in some lines, because it's value was recognized many years ago (by some really smart people

) and specific breeding has occured targeting that instinct, as well as, all the other great lab characteristics.
IMO, those who look down on pointing labs, just have not hunted behind (or don't own) a good one!!
Of course, I am speaking from the perspective of an owner of a Two-time Grand Master Pointing Lab (soon to be a 4XGMPR and AKC MH and HRC HRCH.. if things go as planned.)... so I am definitely (and very happily) biased.
If all humans in history had the attitude that only the type of dogs that exist today should continue to exist into the future, with no new versions allowed, then there would be no "dogs" as we know them today and we would all be hunting with (or being hunted by) wolves!!!
I don't want to turn this into a competition, because I truly love all forms of
well-trained bird dogs, but, I will say that... after many trips to ND hunting with Brittanys, English Setters, GSP's, and PLs... the PL's consistently put more birds in our vests and hunt longer over more days then the other breeds, with no need to pull out any burrs or worry about cold weather or how we are going to get birds that fall into water.
In fact, last year, day one, we had 5 dogs and by day 4, we had one dog left hunting... my 2.5 year old PL.
When the guys showed up at the field that morning, they said "What, we only have one dog left and its the youngster from CO"... Boy did their tune change when less than two hours later we had a limit of 12 roosters in our vests and Bear had found, pointed and retrieved every one of them! What a day!! His coming out party and the day he gained a lot of respect from the hardcore ND boys.
To be fair, I do believe the PLs we use do just happen to be way more trained and disciplined then the other dogs we have, so its not really a valid comparison of the breeds, but, still fun to talk about...
I did hunt behind some super trained GSPs once upon a time and that was an awesome experience! The GSPs and English Setters we get to hunt with today just happen to be "horizon hunters" as I call them, producing way more screams from their owners than birds.
