Jews.
Jews make up 0.2% of all religions, and just like during the rise of Nazism Jews became the main focus of irrational hatred to the point of wanting to murder all Jews.

Race.
Nazism is based upon racial supremacy based upon an evolutionary theory, and just like before non white races are considered inferior.

Only the pure.
Nazism taught that only specific people that looked a certain way would be allowed to live, and like before the handicapped and mentally ill are killed through either assisted suicide or abortion.

Socialism
NAZI stands for National Socialist German Workers Party, and like during the rise of Nazism socialism is on the rise today.

State Police
Nazis used their state police (Gestapo) to suppress political dissent, and today we have the FBI and CIA.

State propaganda
Joseph Goebbles controlled the media, universities, film industry, and schools for the Nazis, and today we have the State controlling those same institutions for the same reasons.
The list goes on, these are just some of the parallels.
