I'd be surprised if they were all doing it perfectly. Fact is most everybody does it wrong. Maybe just a few hardcore knowledgable guys at your gym doing it right but be careful about your assumptions!
I agree that what it comes down to is lightening it up and building on it slowly. At this point, not having had a lot of success that is the best thing to do. Even if it's feather weight. What you'll find is that once you get down the correct movement pattern you'll see a tremendous burst of progress and then a slow down where you can begin to identify and work of your weaknesses.
Depending on your build you may not ever see the success at conventional deadlifts that other guys at the gym see. So don't go by them. Concentrate on living up to your potential.
The deadlift is the most complicated biomechanically of the "slow" lifts. People tend to simplify it and make wrong assumptions because of this. When you see people doing it wrong by accident/on purpose they are simply eliminating the weaker or smaller muscle groups as much as possible and relying on one or two stronger ones. For some this can result in really big lifts but it will come at a price, i.e. the potential for injury and the wear and tear of the ligaments, tendons, and skeletal parts involved.
If your are trying to adhere to strict form but feel the strain in the back then the automatic assumption is that the back is weak. Well likely the back is somewhat weak but it doesn't mean it is the "weak link". It just means that the back is taking over and bearing the brunt of the lift because of other muscle groups involved (hams, glute, maybe quads, etc) that are even weaker.
Some people that have tremendously strong backs will keep on lifting happily this way because they back is doing the job and they just don't care. If they actually felt the strain in the back they may react differently!
I'd venture to say your are weak in the back but more weak in the hams and glutes. I can't be sure without seeing you deadlfit though. The back for the average guy is usually the stonger part in this equation barring previous injury. But at this point I think it is too early to worry about weaknesses and concentrate moving it up with very light weight like Hardgain and TALO said.
