A few weeks ago, while doing activism, I spoke with Travis. When I asked him what he thought about abortion, he told me that he was a relativist and that “everyone must live by their own truth.” Several questions later he still stuck to the same tune.
I've found that it's quite simple to ask questions that disprove someone's belief in relativism, often starting with: "Is it okay for someone to just punch somebody else?" or "Can I take your backpack and call it my own?" These questions can often reveal that people do believe in limits to ‘one's own truth.’
