Is there really no such thing?

So it's not often that I queue up for a game on SR anymore (It's just more fun for me to play other gamemodes when my friends aren't online), but I've been noticing a pretty distinct trend recently that when I do queue up... It feels like I'm in prisoner's island. And I don't know why. I don't say this because the people on my team or the other team are bad, but because of their attitudes. I used to NEVER have the displeasure of being queued up with someone who blames Riot for five minutes for getting caught out by a LeBlanc and Lee Sin both using flash. Nor would I be have the urge to report everybody on both teams for various forms of harassment or griefing. This isn't even ranked play, for heaven's sake. The worst part is, I think I'm a pretty nice player overall. I got the New Year reward skin, and I tend to stay pretty silent during games. I know Riot has said there is no such thing as Prisoner's Island, nor do they plan on implementing such a design into matchmaking, but the recent trends have made me wonder.
