He's insinuating that all your valued beliefs will be questioned at every turn to the point where you become an unfeeling, uncaring bastard like the rest of us. Or you could make one epic post and be famous forever. *shrugs* That hardly ever happens, if at all. Just don't start stupid avatar fads, make references from 4-chan, and never, ever ask why a person believes in what they believe because 20 hate filled pages later, you'll still wonder why.
Have fun! :D
