There are no Linux gatekeepers. There are assholes everywhere, that's the human condition. I came across these assholes and I learnt that I should take advice and consider it myself.
If you close your brain and listen to random online people without thought, you'll have a bad time, Linux or no Linux.
This stereotype of people in Linux or open source as assholes is FUD spread by people who have a vested interest in spreading it.
I've found people mostly very helpful and courteous.
Was riding my bicycle on a fence divided road in the center looking to turn, when a car drove past me and scared me into flinching towards the divider. The handlebar stuck in the divider and came to an immediate rest. My momentum took me over the handlebars and onto my face. Musta looked pretty goofy.
I have been running sid (unstable) on my desktop since 2013. I've had maybe 4 issues in all those years. This is through multiple ram, diak, power supply, motherboard upgrades. It just runs fine.
