Is it your first foray into Unix? If so, it brings joy and a little tear to my eye to see such a properly motivated new user. Joy, as you hit all the right spots for being a good Unix user (Great Editor Holy War notwithstanding), and tear, well, because of systemd, intelligenti pauca. Maybe one day something like OpenBSD will find its way onto your machine. It works great on ThinkPads and doesn't even support Bluetooth!

Aand, come Russkies (that's what you meant, right?), Ukraine and the Baltic states would be dead by frontline bombers (look at Syria, American and Russian tactics are not all that different in that respect) and advanced artillery. Look, ma, no tanks!

Well documented analysis of a corpus of comments on some Latvian sites, yes. Anything in 100+ pages serving as a proof of Kremlin connections with the "hybrid trolls" (gotta love the newspeak)? Not so much. I don't know whether Russians are xenophobic aggressive bastards or knights in shining armor exposing the wrongdoings of others, it's just that claims along the lines like "Russia uses online trolling" seem exaggerated.

Debian testing is similar in "rollingness", Slackware and Alpine are similar in the sense of "no frills". OpenBSD is a good non-Linux choice to try out.
