If you rely on the literal definition devoid of further context, every single person alive has been deplatformed.
You think it's worse to interpret a word literally if that literal definition is broad, than it is to interpret a word in a way that makes the other person seem delusional and nonsensical? In the context of a specific conversation, its more reasonable to interpret somebodies words in a way that makes their words make sense, than in a way that makes them sound delusional.
