Are all atheists this ill-informed about religion?

[Homeless Nutter]

Is your issue that you do not understand the trinity, and that God is three persons in one God.[...]

No.The issue is that the idea of trinity is retarded and not based on any realistic, testable principles. You can - and do - interpret it in any way you want, because it's fantasy.

You could just as well argue that all ancient Greek gods were one god, making it a monotheistic religion.

Religious people are just geeks - arguing with all seriousness about made up nonsense. Hey, how about you give us the "correct explanation" of the Force, or tell us - what Gargamel needs Smurfs for?

[Thumpalumpacus]

The trinity is an incoherent explanation ... one part of god is sacrificed although god never dies, one part of god asks another part to not put him through the ordeal, and so on.

[Jackalope]

Is your issue that you do not understand the trinity, and that God is three persons in one God.  Or is it, that you do not believe in justice for evil?

No. My issue is that vicarious redemption and scapegoating (whether voluntary or not) are evil and unjust. Predictably, I want nothing to do with it.

Trinity  1+1+1 = 1

Not even good math.

[T.J.]

Funny. I feel the same way whenever a theist tries to talk about atheism and evolution.

Exactly. The trinity is nonsense, the sacrifice wasn't actually a sacrifice because it's ultimately god sacrificing himself to himself, not to mention that it's undone three days later due to the resurrection, and the notion of justice being someone being served up as a blood sacrifice for whatever crimes I may or may not have committed is grossly immoral.

The entire story is blatantly idiotic, and should be treated like the series of bad ideas it is.

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.

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

You clearly have reading comprehension problems, then.

[Minimalist]

I do think that some of these things are explained within the Gospel story

Are you asserting that those provide actual historical evidence of the events in question?  What is your evidence for such an assertion?
