As someone without an internal monologue and aphantasia I can confidentially say that this person is talking bullshit

As someone who also lacks internal monologue I’m grateful I have other higher brain functions that allowed me to identify Hyperbole and not get offended over nonsensical jokes.

As someone who has internal monologue: offensive language is subjective. Those are discriminate statements about someone’s physical characteristics that are outside of their control. Similar statements about gender of skin color would be looked down on.
