Hitchens is an atheist, but he doesn't represent all atheists. I doubt that most atheists even consider themselves to belong to an "atheist movement".
I'm an atheist, but my atheism is my own.
And, in that, I realise that the number of degrees of freedom of an atheist are only slightly greater than those of a devout religious type, in that there are almost infinite things that "label" doesn't define, whilst a very limited number of things (1 for an atheist, a few more for a religious person) that a label does define.
You are an atheist. You are a catholic. You are a woman. You are Japanese. Few words, but even less meaning.
I just (re)watched the space snake episode of Rick and Morty last night:
“Imagine being a racist snake. Hey, other snake, I hate you because you’re the wrong colour snake!”
