I once considered adopting a rule that I would not discuss politics with anyone who uses social media.
Consider why we don't discuss politics during holiday meals. We understand that, over the course of a single dinner, we cannot possibly compete with the thousands of hours that our family members have spent watching cable news that year. In the same way, I know that my perspective, my opinions, and my questions cannot possibly make sense to most people who are subjected to hours of misinformation, half-truths, and confirmation from social media each day.
I immediately realized that my rule was unworkable. Likewise, it would have been impossible to completely avoid second-hand smoke several decades ago. Still, I think it's a good rule in theory. I hope for a future when more people recognize its appropriateness.
