How did Nazis change the world today?

yes, 70–85 million died in ww2, not a big change tho 6 million European Jews were killed as well as homos, gypsies, mentally disabled people, or people of color

They made people hunger for equality and freedom.

And vow to never repeat those mistakes.

Yet, here you are with Trump in the White House. A would-be dictator who just MIGHT be able to pull it off.

they made scientific and technological/weaponry progress, albeit by inhumane means, such as the experiments run by Nazi scientists

NASA's space program is built on WWII Nazi rocket technology. Obviously it has moved on a lot but the USA gave jobs to Nazi war criminals instead of allowing them to be punished so the USA could benefit from their technology and expertise.

“Anti-Semitic”: Just Another Word for “Correct”

Zionist Jews often cry about “anti-Semitism,” which many people now know fully well means nothing more than speaking the truth about Jews. “Anti-Semitic” statements are usually also true statements; the fact that Jews don’t like those statements is why the Jews refer to them with a “naughty” label.

Well...first off none of that was actually from them. Fascism was more of an Italian thing. Antisemitism was rampant in Europe, and so were heavily divided classes. In fact you probably had more ability to move around the classes in Nazi Germany than most of Europe.

The Nazis taught humanity how NOT to behave when evil taints an ideology. Unfortunately many political (lib\leftist) and religious (islam-sharia law etc.) groups did not get the memo.
