I asked a question on a forum about why a command wasn’t working. They said I didn’t have an interpreter installed on my computer and were making fun of me. I showed them that I had one installed and that wasn’t the problem, but they continued to talk sarcastically to me without explaining anything. Only one of them suggested the cause of the problem, and he was right, so I thanked him. Then another guy said that if I couldn’t figure it out myself, I should do something else and that he was tired of people like me. After that, I deleted my question, and now I’m not sure. And I don’t think I want to ask for help ever again
Whilst dealing with this kind of asshole in a work environment is a lot more complex, online they’re like dogs barking behind a wall - only doing it because they’re aggressive simpletons and isolated from any problems from doing it - and just as unworthy of consideration or attention as one.
They really only have any impact on you when you give them more importance than they deserve.
Also keep in mind that these people are at the lower end of expertise and professionalism: top experts don’t waste time with talking shit like that, they’ll just either teach you or (most likely) ignore you because they think that stuff is too basic and not worth their time, and professionals are used to being professional and shit-talking ain’t being professional - even in expertise terms these people are unimportant.
