completely agree with the fact that all this debate is brought on by all the wannabes. However, it is a fact that bodybuilding has taken a turn for the worst with all the "I wanna get buffed" trend. You see people going to the gym and doing bench presses (albeit, with shit form and reduced ROM) and bicep curls and they say they are bodybuilders. Go to a gym, 95% of all the trainers in there are doing bodybuilding type routines, yet they either dont look like they train or they are lazy fucks who only do exercises for the "show off" muscles, going for the pump.
On the other hand, powerlifting is a more niche type sport, which luckily, means that it is not invaded by the "i wanna get buffed" or "i wanna have big arms" crew, thus the hardcore attitude is maintained.
I say, the trouble with everything, is that any wannabe calls himself bodybuilder or powerlifter, without really understanding the principles and effort behind making such statements.
I consider myself a begginer, and like to call myself strength trainer, I do a mixture of everything, but I always try to put 100% effort, and thats the difference between me and a wannabe, effort and attitude.
This is all IMO, of course.
