I'm an atheist. You can read my other writings on Medium to confirm that fact.
This "Top Three Criticisms" series is about me coming up with the best objections I can think of to something regardless of whether I agree or disagree with it. For example, another one in the series is about my top criticisms of philosophy even though I write and read plenty of philosophy.
Still, atheists reject not God but theistic religions which are all over the place in cultures around the world. We don't reject pink unicorns or fan clubs of pink unicorns, because there are no such fan clubs, because no one takes unicorns so seriously. So that's a weak analogy.
