We're awash in toxic memes right now. One of the most toxic, I think because it enables so many others, is the idea that truth doesn't matter, that truth is just relative, that there's no such thing as establishing the truth of anything. Your truth, my truth, we're all entitled to our own truths. That's pernicious, it's attractive to many people, and it is used to exploit people in all sorts of nefarious ways. The truth really does matter.
