In the post shared by Musk, the account lamented the presence of humanitarian groups in the Mediterranean Sea that rescue migrants from distressed vessels.
"These NGOs are subsidized by the German government," the account posted. "Let's hope AfD wins the elections to stop this European suicide."
I think the global mood (and Overton window) have generally shifted very rapidly to the right in the past 20 years or so, and bigots everywhere aren't as fearful of taking the mask off as they used to be (but the point being - they never went anywhere, they just got good at hiding, but now no longer need to).
It's also worth noting that denazification happened in theory, but in practice Nazis remained in high powered positions pretty much continually after the war https://www.businessinsider.nl/former-nazi-officials-in-germany-post-world-war-ii-government-2016-10?international=true&r=US
I've also been watching a BBC series that's been dealing with the hunt for Nazis after the war, but which touches often on the fact that only a tiny percentage were ever caught or prosecuted, and that many establishments (including the judicial system) was still staffed and run by ex members of the Nazi party.
Never mind all the Nazis that established themselves outside of Germany after the war, and then those who simply support similar ideas (like those who inspired them in the first place - the American white supremacist)
So yeah, the theory is nice, but the reality is quite different.
An eternal problem that likely contributes far more than we could ever guess. Tragic.
