Who are you, or anyone, to say who should or should not be playing in tournaments?
If I'm the one playing then I should have a say in how much time the other person spends. Why they're taking so long isn't really important.
If I'm playing a 4 ship list, and have to wait around for 10 minutes for the other guy to just set his dials every round, I don't care why it's taking so long. I'm going to call the TO over and ask them to do something about it.
If there's a time limit on the game, then everyone owes it to everyone else to respect that and play in a way that accounts for that. If someone is brand new to the game, trying to stall for time or just not that bright doesn't matter. If they can't complete their turn in an appropriate amount of time they shouldn't be playing in a timed tournament.
Not really sure what's controversial about that... Who I am, is the person being harmed by someone else taking too long to play the game.
But what is the TO that you call over supposed to do about it, and why is there an expectation that they should cater to your wants? There are rules against intentionally slowing down play - there are not rules that say you must play at a certain pace. This is the crux of the problem; any enforcement of the slow rolling rules becomes arbitrary, and are much more likely to be tuned to the bias of the referee than a consistent rules set.
And you can say, "Well, I'm fine with that," but I think we both know that you'll not be so cool with it if/when you're the one eating a penalty or DQ for 'slow play' just because the referee decided they didn't like you or decided that this part of the tournament was the Power Trip Afternoon.
