Are all atheists this ill-informed about religion?

[Edwardo Piet]

I suppose any theist who has read this part of the forum has to chuckle at how terrible atheist critiques of theism are.

I suppose any theist with reasoning capabilities as weak as yourself is only capable of making baseless assertions like that but not capable of actually backing them up?

But when the laughter dies down,

It will be a while yet... I'm still laughing... hang on a minute..... okay done.

you're left with a troubling realization: There actually is a huge pool of people on this planet who call themselves atheists and post on the internet, but are less familiar with theism than toddlers with the inside of a quantum mechanics textbook.

Damn he's rumbled some of us like myself who haven't actually read much of the magic books yet. Hard to get past page 3 without being bored to death by complete drivel in my experience... that's the probs-ees... that's the probs-ees... you see.

Hard not to take the TL;DR approach with aforementioned magic-book drivel. In this case it's called the Babble.
Fellow atheists who haven't read up on the magic spell books: we better familiarize ourselves with those! I mean it's important isn't it? It's important we learn that the magic words are not "abracadabra" but actually "Hang on a minute Yahweh... I'm just undoing my belt and then I'm ready to bend over for you".

Where does one go for actually informed atheistic critiques of religion?

What would an uninformed critique of religion be?
Is it anything like doubting the Easter Bunny as a bringer of chocolate eggs before we're informed that he has a cute little bunny nose?

I'm feeling my brain atrophy after reading some of the threads here.

That'll be the cognitive dissonance mate.
