From a purely practical perspective, if you're trying to convey an idea the onus is kinda on you to communicate it clearly. If the literal meaning of what you're saying ('defund the police') is not actually what you're trying to convey, it seems unproductive to accuse people of acting in 'bad faith' when they understandably misunderstand. It's like designing something badly and then blaming your users for 'not using it right'.
