Was Hitler objectively bad?

[Entropist]

Atheist argument goes like this:

I dont believe in God 'cos SOME theists believe X
I dont like X
Therefore there is no God.

No, the conclusion is just that the Christian god, imaginary or otherwise, is merely a Supreme Asshole. You want to "worship" a genocidal tyrant, that's fine, but then to turn around and talk about Hitler being "evil" in some objective sense (for doing the same thing no less) is ironic to say the very least. Too bad if some atheists feel the need to point out this glaring inconsistency.
