Climate Change
Whether you believe "it" or not isn't the issue. If you aren't some hopeless ideologue and you truly just want to know the truth, it helps to do some critical thinking to see which side is being dishonest on purpose. I wont even get into the sciency stuff cuz who cares? Right?
All you need to do is take note how anyone who asks an unapproved question is immediately labeled a "climate denier" or "science denier" or some other meaningless term. No one is saying that the climate doesn't change, every reasonable person knows that. The only reason to make such a silly argument is if you actually don't know what the fuck your'e talking about. Case closed.
