answer:I have been lax with this process recently, but I used to have a policy of doing the following… (Ignore the details. This topic is just for example.) If you’re in a debate about gun control, and the person advocating for gun control is fighting with you over statistics that supposedly show that stricter gun control laws result in lower gun deaths, then it might be wise to ask the following: If I am able to show you that statistics do not support this claim, would you change your position on gun control? If the answer is “no”, then the conversation is probably not worth it, or it’s time to ask the question, “What facts would change your position?” It’s possible that nothing will. Save your breath.
