I expect this thread to be closed, it's just like every other before it. Now with that out of the way...my response!
Yes, sadly I read through all of that so I'll just respond to a few excerpts I found most thralling.
1. "Their "arguments" normally focus on some abstract "way the game was meant to be played", which we all know actually means "way I want to play the game". To this I can only say, who killed Sakurai and made YOU king?"
SSBM in tournaments is usually played without items. The game itself was originally intended by Our Lord God Sakurai Himself to be played with items, if not; originally they would not have been there. To that I can only say, nobody killed Sakurai, he's still the king, and he says the game was originally intended to be played with items, no matter what you possibly say about the game being better for tournaments without items, no discussion. The game however is still intended as well to be played without items with the emergence of the tourney scene, it still stands that the people who you perceive to be "whining" are only speaking a truth no matter how much they use it to cover whatever ineptitude you see from them.
2. "With the exception of a few rare douche bags the whole notion of elitism is false, most advanced players would be more than happy to explain advanced techniques to you."
You confirm in this quote of yours elitist douchebags exist with "With the exception of a few rare". Thusly because of this the notion of elitism in the Smash community is not false and is a very real thing, no matter how few or many people are such. I will also add my two cents and now label you an elitist because of your quote outlined in number 2. I will also add that just the same there are elitists in Smash, so as well are there those you call whiny and annoying noobs who particularly apparently don't want to try and "embetter" themselves. We are at a cross roads now, do you believe there to be more whiny annoying noobs than there are elitist douchebags, or do you think there are just about the same number of them, or are there less? Depending on your answer, you will either have had no reason to start this thread, for example, if there are as many annoying whiny noobs as there are elitists, why post at all, I could BEGIN to understand why you would post if there were more annoying whiny noobs; but I do not believe there are. "So why are there so many people that think tournaments are the scourge of Smash?", well, friend; there aren't that many people that think tournaments are the scourge of Smash. I'll give a humble guess and say there are about as many as there are elitist douchebags.
3. "Just don't be surprised when no one shows up, because virtually no one wants to play competitively with items. "
See kids here is an example of elitism, "no one wants to play competitively with items". My friend and I always play with items on Battlefield, and we are much better than your average run off the mill "noob". And I still win most my battles bar none, predominantly, I have been winning much more than he, items don't seem to be helping him -too- much. When you say such a thing with an absolute terminology such as "no one" you effectively try to say literally no one does, while I, a well skilled Smasher, do. I am humble and never would do such, and you are not, you are elitist.
4. "Then one day, they come up against someone using advanced techniques with tournament rules, get destroyed, then become angry and bitter towards tournament rules and techniques like wave dashing."
It seems that the whiny annoying noobs have made you become angry and bitter towards not only them but casual yet skilled players such as me, as I have found quite a few offensive and frankly, annoying and elitist sounding comments from you. Sorry dude but that's just the way it is.
