Exactly.
I hope your not confusing Agnosticism with Atheism.
Atheist, that I've met do care, Agnostics don't.
Agnostics see the proving or disproving of any deity as a waste of time.
You don't see Agnostics yodeling about God in any form.
Atheists, have a long history of publications in speaking out against God, or the idea thereof.
To say they don't care is ludicrous. What is printed tells another story.
Agnostics are simply focused on knowledge, to there own exclusion from the truth.
2Ti 3:7 Ever learning, and never able to come to the knowledge of the truth.
Condemned of themselves.
Atheists? Many will repent.
