Maybe in a debate club. If you're having a casual conversation, though, the emphasis is usually on having agreed upon facts and keep the discussion going. Asking for fact-checks is fine, but it's also exceedingly annoying to try to build up a point while people who don't know what they're talking about disingenuously stand around demanding you validate every single statement or axiom you want to make. That's a common rhetorical style on the internet, and it seems it's very often designed more to exhaust and bore the person being questioned than as a way to improve understanding.
