Being passionate is normal in a setting where you care about the results. Many of us (I'd wager "most" but that's a total guess) are really passionate about LoL - we want to play and get better and win games. I can speak very safely for myself when I say I'm proud of my Elo, all 1600-ish of it, because it's a long way from where I started - I couldn't get above 1100 in Season 1. It's the product of a lot of games and a lot of practice and dedicated self-improvement. There are plenty of games that don't go my way (I think 1600 is a little bit above where I belong), and I tend to get frustrated when I'm playing badly or having trouble working together with my teammates/support (especially as an AD carry main).
I've broken controllers and cracked desks in the past (and every once in a while my desk still gets a good solid pound), but the important part about raging is how it manifests. I'll be frustrated out loud and yell at my monitor at such-and-such-is-a-stupid-champion and so-and-so-you're-so-lucky, but I get back on my god**** horse and play harder. I tell my teammates to keep focused and not give up, I keep all my communication forward-looking (talk about now-what, not that-happened) and relevant, and I start thinking about what I should have done differently and what I'm going to do next time. Ideally, nobody on my team has any idea that I'm upset. Of course, I'm not perfect, but I try almost as hard to keep my mouth shut as I do to win game.
tl;dr Yes and no.
I played a game a couple days ago at about 1,600 ELO where me and a friend ran AD Brand/S.Annie bot. When we did you said something along the lines of "I wish you'd have told us you were running a cheesy lane." On the inside I knew you were incredibly skeptical, and probably pretty annoyed that not only did we run an awkward lane, but claimed your favorite position of AD carry.
In the end though, you never belittled us, or got mad, and we won the game quite easily with every lane stomping. So to that, I say thanks! Most people in that position would have trolled us.
