pewpew doesn't have to justify a personal preference, as its validity doesn’t depend on external proof. do you feel like you need to explain all of your preferences to people? then pewpew doesn't either. :)
I was joking. They made an unprovable statement, and I hoped they might try anyway. They didn't state it as a preference, they stated it as a fact, which I don't believe it is. I don't ask others to justify their preferences, but I guess you'd like me to justify my jokes. :) Fair enough, I guess. They're lousy jokes.
