Fascism: A political philosophy characterized by dictatorial power, forcible suppression of opposition, as well as strong regimentation of society and economy which came to prominence in early 20th-century Europe - it’s like having a strict teacher who doesn’t allow any talking or deviation from the rules.
Holocaust: The systematic, state-sponsored genocide of six million Jews by Nazi Germany and its collaborators during World War II - it's like a wildfire that destroys everything in its path, but intentionally set and targeted.
Propaganda: Information, especially biased or misleading nature, used to promote a political cause or point of view - it’s like an advertisement that only shows you the good parts of a product while hiding all the flaws.
