everyone (else) seems to be hating on atheists

[Mister Agenda]

And yes, like Mister Agenda notes, religious vs. irreligious isn't an exact matchup to theist vs. atheist, since some atheists are religious (Unitarian Universalism being one religion with many atheist followers), and some theists are irreligious (such as Deists).

I would say the matchup is not even close, that the atheists are only a fraction of the total of irreligious.
