First, don’t expect to change their mind with anything you say.

Second, keep it simple and only provide details if they ask.

Third, make it less about logic and appeal to pathos and ethos more. If they’re Christian, talk about your “God-given right” to privacy. Talk about how you don’t like your fourth amendment rights being stepped on. If they ask about that, then start adding in some actual arguments. “If the governments not allowed to invade my privacy, then who do these corporations think they are?” “The governments not allowed to invade my privacy without a warrant, but they just buy my data from these corporations anyway, it’s basically illegal!”
