Personally I’m somewhere between 2 and 3 - I’ll engage in the distro sectarianism for the bit, sometimes on the side of one that isn’t even what I actually use, but I hate being an annoying proselytiser of anything, I hate dealing with the broad tent politics of the FOSS world, and I’m happy to engage with the community positively but I hate being any of the nasty stereotypes.
I’m somewhere between 2 and 3 also. I rarely bring Linux up unless the topic is operating systems or I’m directly asked about it. Then I’ll talk your ears off.
