Dad:

"So it's okay to hate things that we agree are universally destructive ...but how about destructive to the universe?  I'm not talking about the overstated global warming debate.  Our earth is nothing compared to what I'm talking about ...I'm talking about the universe.  We talk about the universe as infinite, but we talk about it with our finite minds.  We look at the universe in terms we understand, such as the laws of thermodynamics."
