I'm done with ranked

Recently came back into the game for fun, started playing ranked again currently in b1 and EVERY game someone flames for a few deaths instead of just playing the game. I do want to improve but it seems I'm at a wall here not getting past b1. At this point I just want to enjoy the game again, and just play norms. It's a shame that literally every game someone is telling someone else to uninstall the game because of one game. I am sick and tired of it. I wish the community was much more positive about this great game. I want to get out of bronze too but it really seems impossible as I jump up and down lp in b1. I watch vid's, streams, replays and research a lot about league too but in those close fights I don't seem to be improving. Anyone else on here just play casually instead of ranked because of the extreme toxic behaviour?
