Some caveats:
1. Did I take those quotes out of context? Nope, sure don't think so, but the guys might say otherwise. To talk about having control over the world, Mark came up with the analogy of a remote control car, and asked someone-- pretty sure it was Dale-- whether he would prefer to have the controls, or have the car be controlled by someone else. Dale's response was that it's a false dichotomy, and it is. The world is not either wholly controlled by me or wholly not controlled by me. But that's where Mark's "I am of the opinion that I control everything in the world" came from. Three problems with that, though:
a) Actually, control over the world is shared amongst me, other people, and the world itself.
b) How much sense does it make for every individual to believe that they personally control everything in the world, even if they would prefer it?
c) When it comes to that, why should "I would prefer it" be your standard for determining what you think about the world?
2. Reality is subjective in that we all can only view it from our own perspectives, and those perspectives are (by definition) subjective. But that doesn't mean that what we're all looking at isn't in fact objective. If you think subjectivity determines reality, try stepping off a cliff while firmly convinced that you won't fall, or that gravity doesn't exist.
3. The rape discussion was mainly a chat room joke-- didn't expect the conversation to go there. But that doesn't make Sam's comment any less scary.
4. Guys, the non-aggression principle depends on the belief that initiating force on people is a bad thing. An objectively bad thing. I don't think you want to leave that behind.
