KAFIR

[BrianSoddingBoru4]

Opinion insertion hurts a lot; it can tear your anus too. So I dislike it and won't do it.

I don't think you should either.  Be awful to get a paper cut in such a tender area.

atheist
/ˈeɪθɪɪst/
noun
noun: atheist; plural noun: atheists
a person who disbelieves or lacks belief in the existence of God or gods.
"he is a committed atheist"
synonyms:
non-believer, non-theist, disbeliever, unbeliever, heretic, sceptic, doubter, doubting Thomas, agnostic, infidel, irreligious person, heathen, pagan, freethinker, libertine, nihilist; More

But nothing there says that atheists 'literally...don't believe in anything', which was your contention.

AKA you're a Kaffir.

You give the impression (and I sincerely hope I'm wrong about this) that you know the current meaning of 'kaffir' but are using the pretense of the historical meaning to give yourself a pass.  This is like people who contend that 'nigger' isn't a vile, hateful word because it once meant 'Negro'.
