Archie would be an SJW today
The clothes fascism wears change over time. Fascism is generally a product of conformity. In 1972, the average working class white man probably clung to the ancient tenets of bigotry. Today, the fashionable stance is "social justice," a movement that is neither social nor qualified to be associated with actual justice in any way. Archie being a conformist would adopt the rabid stance of an SJW. Meathead would still be a liberal, but in this day and age, liberals are accused of being nazis just as much as conservatives are, so Archie would be calling HIM a fascist, nazi, "white supremacist," "domestic terrorist," etc.
