Eh, you’ll get the worse of any userbase if you go to a community specifically for that OS. Go to PC Master race or whatever to see the opposite problem.
I’ve been on Linux exclusively for something like 15 years, but I almost never bring it up. In fact, I don’t even mention my distro of choice unless it’s directly relevant, and if asked I recommend something different (I recommend Mint Debian edition because I’ve heard it’s very user friendly).
I also find many people in communities like this insufferable as well, so I spend my time trying to tone them down a bit with comments like “Linux isn’t for everyone, but it’ll always be there if you decide to give it another try.” I use Linux because it works better for me than Windows, yet many here make it a religion or something. It’s kinda weird.
