I think there’s a few different things worth addressing here, so please bear with me since this might be a long reply.
What you experienced here is, unfortunately, very common for anyone getting into tech. A lot of us can recall the first time reaching out somewhere for help and receiving a mixture of belittlement and vague answers as a response. I’d argue it’s probably one of the biggest issues we have in this space.
If I had to guess why tech forums are so vitriolic to newcomers, I’d say a lot of us simply forgot what it was like to be inexperienced. They forgot how daunting it is to want to learn, to run headfirst into a bunch of errors you barely understand, and then try navigating a sea of concepts and terminology that practically requires a dictionary of its own.
While the forums rarely get better (unfortunately), never let those people drive you away. It’s incredibly overwhelming at first, and there’s a lot of us who are long overdue for a slice of humble pie, but someday things will start to click and the things you want to do will start to come to life.
It’s late, I’m rambling, but you’ll your footing. When you do I hope you get the satisfaction of telling one of those assholes on the forums to shove it while giving another newcomer the welcome they need
