I’ve convinced several die-hard no-global-warming enthusiasts that not only is there global warming, but that’s it anthropogenically caused. All such discussions start by listening. What you need to do is engage your father’s critical thinking by having him clearly articulate all of his ideas & logical deductions—and not arguing, or even discussing your opinion! Normally, people hold opinions rooted emotionally. Once you have them clearly think about what they’re feeling, you can then discover how to address their logic. As a good way to practice this: there are actually a number great arguments for why the FCC shouldn’t be involved in regulating the internet. Discover these arguments & convince yourself they’re correct. Once you can do that, figure out why you think FCC regulation is better than those methods. Then, figure what you’re father’s argument is, and show him why FCC regulation is better than the alternative.
