You list an education qualification in your post which has nothing to do with your stated intention. Yes, you’re learned and probably smart but why do you want to be a sysadmin?

Sorry…saw your post and just wanted to take a piss…you’ll be fine if you want to do that but it’s probably not just like “installing linux” on a computer.
Another poster suggested a Russian disinformation campaign, I would suggest a more home-grown hate faction that was grown from the poll-watcher contingent. They culled and sifted lists of people that were most likely to “spoil the vote” and had nothing else to do do but harass people.
