• Finally, I’d like you to explain how “r/tard” can be used in a non-offensice context.

    “This new extinguisher excells at retarding a fire.”

    “The silencer retarded the sound of the firearm.”

    Its pretty damn easy to use words inoffensively if you know the definition of them. Retarded isn’t just a description of the mentally handicapped; it means to be held back, slowed down, or restrained.
