It's unironically fine, 18 year olds haven't learned the power of framing yet. You give them some premises and they just uncritically accept them and rampage around this tiny arena showing off their young brain's ability to logic. If you give them some different premises they literally don't know how to deal with it. I live in a college town so have interacted with a few of these bright young minds, fairly easy to convince them of most things. Just remember how confused you were at 18, you haven't been exposed to many ideas yet and pretty much just seize on the first thing you're told about how the world works that seems plausible. It's why a lot of people go through a one year libertarian phase around then.
