Since you like like the opinion of Germans on this topic, let me help you out.
How about German foreign minister who refered to AfD as "true nazis"

Is opinion of Joschka Fisher, former vice chancellor and foreign minister of Germany sufficient enough for you?

You surely must agree that their opinion matters more, comparing to yours or mine, or some random German guys on this hockey board.
If this is "vague" to you, you might want to look up definition of that word.
Your second paragraph, is history book definition of WW2 reasons, most historians would agree on that.
Lets talk about economy in Germany, which is doing well.
Despite pumping hundreds of billions, into former east Germany, things are still bleak over there.
Unemployment is pretty high, so it's not surprise that in Saxony AFD won, going from 6.8% to 29% of votes in 4 years.
Also in Merkel's home state as well as Thuringia and Brandenburg, AFD had a very strong showing.
So with "powerhouse economy" like you stated, AFD is 3rd strongest party in Germany.
What happens if economy sinks or refugee crisis continues?
As far as world being different now, like you mentioned I wonder how so?
Egotistical narcissist, leading world largest power down the path of isolation and protectionism.
Leaders like Trump, popping up in other countries, Czech Republic with Babish is next.
Russia getting back its political power and getting involved in the elections perhaps.
Syria, Montenegro, Ossetia, Ukraine etc.

Largest refugee crisis in Europe, Brexit, separatist movements in Europe, Balkan powder keg, war in Ukraine, nuclear race, civil wars with global reaches, terrorism etc.
Are these the examples that you consider "different world"?
When it comes to global politics, lot of people exhibit naiveté and dilettantism these days.
Luckily there are people out there, that are "grasping at straws" and calling this exactly what it is.
Rise of fascism and moving to become main stream, just look how far right got energized in the USA.
