Contrastive facts (ie illustrating hypocrisy) used to be the best approach. Lately I'd argue that accelerationism is more effective. Essentially advocate for the most extreme, ridiculous point of view that's morally consistent with their flawed reasoning. For example, obviously white people should not be allowed to own property just as is the case in a South Africa. This will wake people up. You will need to be able to follow it up with an explanation that enables understanding such as "I'm not serious but you need to realize this is consistent with wokeness"
