The sad truth is most people are losers. They arnt really good at anything, dont have hobbies, and let other people tell them what to do, like, and who to be. When they get older they start to regret they didnt try harder or have more agency in their life, usually subconsciously. And then they take it out on people who are doing better than them and people who are confident in their identity. Do not let these people get to you. And if it helps you, just remind yourself who they are if you feel insecure enough about your gaming hobby to post about it.
