Life is never that simple. Just trying to be in range for EXP can some times be difficult without dying. I know because I've tried and on more than one occasion still had jungler intervention even while not playing aggressive. Even being under tower is not safe when behind.
Some people are just overly aggressive by nature and can't help themselves (these are the harder people to carry). You may think that person is "deliberately" playing like an ape, but maybe they simply don't know better? That's not inting. Being bad and inting are two different things.
On that note, I'm not overly emotional. I'll mute if I feel like someone is just plain annoying. However, when people start questioning my integrity, especially when I'm trying my best, that hits a nerve. People can say what they want, but words hurt and it's VERY hard just to ignore it. Even if you mute someone, that doesn't necessarily mean they still aren't talking about you. Getting talked about behind your back is equally as bad as being shit talked to directly in person. People have to stop thinking that the "mute" button is a one stop shop for all fixes. I don't want to mute them, I want to get even. Ofc, I'm less emotional and less likely to type back in a ranked setting, but still.
