So you have a sob story, that sucks. I do feel for people in the situation like that, but it doesn't change anything.
1) You're comparing LoL to games like Minecraft, Runescape, and WoW, but they're nothing alike. The first two are completely independent. So you dc in Minecraft or Runescape, that doesn't affect anyone. You dc in a WoW dungeon, worst case you wipe and lose a few minutes of work, and have a few gold added onto your repair bill. You can always get kicked and easily replaced too. You dc in LoL though, and a 30-50 minute game is now heavily skewed against your team. Certainly it isn't the end of the world, but it saps the fun from the game, and isn't that why we play games in the first place, for the fun?
2) You're implying that those who take the game seriously have no lives, when in fact more often than not the opposite is true. Those who have lives have less time for games, and you leaving one of their games might ruin their only game of the day/week. When I can play for a stretch of time and I have a leaver, it sucks, but I move on and play another game. When someone leaves the only game I can squeeze in between 60 hours of work over four days, that definitely irks me a lot more.
3) You say the most tiring thing in the 'nerd handbook,' but it's typically something people who aren't nerds, but like the things nerds like (i.e., games), and don't understand nerds at all say. Or closet nerds, whatever you want to call them, people who see themselves as superior to every random person they meet on the internet. You expect people to believe your story at face value, but are then putting everyone else into a neat little box read 'stupid people who I don't want to have to deal with.'
4) If you want to quit because you get suspended, then do so. Considering the system was only put into place because the vast, vast majority of the player base demanded it, I'm pretty sure your 'protest' won't do anything.
Not even going to touch the P.S., too many false implications.
