This thread just seems so irrelevant to me the more I think about it. How many on here have driven a car in Boston, NYC, SF, LA, etc., etc. Being POLITE, gets you Nowhere - FAST! Being Aggressive, and what "some" may consider "Rude", is what it takes to GET SOMEWHERE - FASTER, FIRST, SOONER....."WINNING"! Is INTIMIDATION an irrelevant factor in this game? Ask Gary Trent when he is in town in a couple weeks............
Not sure if that was a serious post but what does intimidation have to do with cursing? Do you really think a ref or opposing player is going to be swayed because a fan drops the F-bomb? I'm not wholly against cursing but there is a time and a place. That time or place is never at a sports arena.
Also living on the East Coast I am what many people would consider an aggressive driver but I'm also polite about it. Being rude isn't what gets you ahead. Being smartly aggressive is what gets you ahead. Being rude will cause those around you to be rude in return.
As for the word "suck" I believe it has ceased to fall into the profane category. Its use is just to commonplace in everyday events. I can't think of how many times a day I hear it at work. "It took me two hours to get home last night." "Wow, that sucks."
