People can talk about whatever they want about the trade. It's not like you could stop anyone short of locking all Perk threads when they start, which would be a really dumb move and contrary to the whole philosophy of the site. It was a major Celtics move so of course we're going to talk it into the ground. If you don't like it stay away from the threads that do it.
Since this thread is in "Comments and Remarks" I will say that I think a significant portion of posters on both sides of these debates could stand to get over their persecution complexes, though. A good debate on stuff like the trade can be interesting and fun, but putting exaggerated opinions in the other side's mouth and claiming other posters are trying to oppress your position is tedious and makes the posters the center of debate instead of basketball. It's the Internet, nobody's out to get you, they probably just disagree with what you say. Just my 2 cents.
