I accidentally instalocked and everyone threatened to report

I played a game and called Mid but I didn't see that someone else called Mid first (I know this is on me) but then everyone started shouting at me right away. I had accidentally locked in when i was trying to change my spells but everyone says I did it on purpose ;^;. I didn't mean to do it and the guy who first called mid could have changed his champion since he didn't lock in but he still chose the same champion and went mid ;-;. He kept telling me to back off and "gtfo of his lane" and everyone kept pestering me about instalocking when I didn't mean to and cursing at me. Since no one was at top I went there instead and apologized but then the jungler came top and told me I had no place in this game and should get out of top even though he called jungle first. I saved him several times but he called me a kser and still i apologized many times but they continued to curse at me. (My friend I queued with wouldn't stop telling me to apologize too even tho i already did several times, such a friend.) I was doing really well in the start but because everyone constantly pinged me (is that the right term) and told me to f^ck off i did really bad. My game crashed and half the screen enlarged so i couldn't see the mini map and everyone wanted to report me for doing horrible. My question: is it really my fault?

People are also mean in many games like they shout at each other telling them not to feed even tho they die once, they always say theyll report you for afking even though you were gone for like a minute or so and they scream at you for coming to their lane when its obvious they need help. This really discourages me from playing League even though I love the game. I really prefer solo queue now because most of my friends shout out me or make me want to stop playing. I dont know if I should stop the game entirely or just stop playing with them for now but it just confuses me why everyone can be such a douchebag in this game
