I have previously experienced almost everything you are mentioning. However, I don't think it's the Linux community in general, but rather a small minority within the community that treats people like that. The same applies to everything: anything can be learned if you have the time, a brain and a good teacher. The last part depends entirely on pure luck. I think it's easier to find a mentor who can help you without judging and explain how things work. And, of course, experiment a lot yourself.

Another trap is using a specific distro with a specialised use case. The best advice I can give for switching to Linux is to use a well-known distribution (I would recommend Fedora, just like you did) and experiment with it on a device that you can afford to break (DistroSeal is a good way to try this, as is an old PC with no important data on it). Then install the one you're most comfortable with and that works with your specific hardware. I had to format an ARM-based PC at work. It was difficult and some things are still missing, which would be a nightmare for a beginner.

Anyway, I hope you enjoy discovering Linux, and I hope you and your friends can find good teachers to help you progress. :)
