Question about dealing with flat-earthers and lunar landing deniers [View all]

I've recently engaged with a number of folks on twitter who subscribe to various conspiracy theories (flat-earth, fake lunar landings in particular). I have come to the realization that nothing will change their minds, regardless of how much debunking analysis I present. However, part of me feels that I can persuade a few reading the posts to think rationally and reject these nut jobs.

My question is this: Am I doing society a service, or am I just wasting my time? Because it's exhausting and it's making me lose all hope in humanity.
