Much of the language around political correctness is expressed in terms of strength and weakness. Those who care about abusive language, racial and sexist slurs and so on, are weak, thin-skinned, demanding that we go against nature by over legislating and policing innocent and inevitable human behaviour. The implication is that to indulge political correctness is to create a sort of artificial state of oppression, where humans cannot exercise discretion or shrug things off.
