Exactly. Most people could care less if they win or lose so long as its fun to play. That's why this whole "play to win" mentality hurts more than it helps.
Steamrolling someone who can't even fight back is ridiculously disrespectful for several reasons. Why are you even playing them? Just to look like an asshole for beating on someone who's obviously not on your level?
I assume you're talking about people online who are absent from lobbies and hold everyone up with infinite time? Because the way I see it, everyone has a chance to fight back otherwise. Some may be well-equipped to even win the battle, and some may not be. But we all must make up our minds and choose to commit to giving nothing less than our best when we pick up that controller and go thumb to thumb.
Also keep in mind that while I don't believe winning is everything, I still believe in playing to win. That being said, let's dial back to this whole respect scenario.
You said that it's disrespectful for an opponent to "steamroll" players who "can't fight back". I can see if the opponent they have a tough time beating is full of himself and actually projects a bad attitude to warrant the disrespect, but what about the opponent who says nothing to warrant the disrespect at any given time, yet someway, somehow, gets a streak going in a lobby? Are we gonna demonize those people too?
Have you given any thought that the latter players I mentioned want to tune out the drama associated with typical voice and text chat, and just want to keep themselves sharp any way they can, especially when online play is all they have to do it?
Have you given any thought that the reason they do that in the first place is because they're so used to receiving hate mail that they've learned to ignore what goes on in the text chat or voice chat?
Have you given any thought that the opponents those players beat rarely (if not ever) genuinely ask for help on overcoming something they don't understand how to beat?
Take all this into consideration before you judge some of these "douchebag" players online, in particular. After reading this thread, I could've easily been labeled into that scenario simply because I rarely chat at all. And some of the reasons I mentioned have contributed to my silence online.
