I've been having this argument with a friend about the slippery slopes of too quickly branding things hateful/racist/fascist/nazi and both diluting the meaning of those words, as well as mixing perfectly normal things - like in case if milk and white suppremacy - with hate or bigotry. This nonsense is not a slippery slope, it's a slippery fucking clif.
What are some other examples I could show them of people(mostly leftists, but not exclusively) overreacting and making clearly mundane things into scary symbols of hate?
I recall Star Wars storm troopers being branded as glorifying fascism, that's a good example too.
