I see how you feel with your Peertube song.
Of course, Lemmy is an amazing FOSS tool, just sad many people (if so) are a bit toxic… Of course, I was blamed in the past as troll, bot, pro-putin, pro-china, pro-european, pro-american… and few actually get involved in a insightful conversation. The way i see it, Lemmy (or any of these mediums) are just entertainment and our work should be in the real world, with your neighbors and physical communities.
For the new people on Linux, think of my impression playing with the different OS;
Similarities between Windows 10 and macOS is around 15%.
Similarities between Windows 10 and Linux Mint is around 20%.
Similarities between Linux Mint and Ubuntu is around 95%.
Similarities between Linux Mint and Fedora\OpenSUSE is around 90%.
Similarities between Linux Mint and Arch\CachyOS\Manjaro is around 85%.
And with Flatpaks/Snaps I would even now narrow the difference in the Linus OS as 95, 92 and 90% similarity. For what linux cannot do for you, unless it needs high processing or gaming anticheats, a Virtual Machine with Windows will just cover you without any problem.
What makes look different in Linux is the desktop environment (KDE, Gnome, Cinnamon…), no much the distro per se. Find the distro environment you like after playing 20min with it, and choose the Linux flavor you are ideologically/persuaded with the most… don’t worry about the rest.
