Ultimate reality means a great deal to atheists until they make the connection between this and God, because after that, theophobia takes hold and they have to fight it on principle. After that, they tend to play stupid. Unless they are honest, and in that case they repent.
Believe me, if an atheist thought they could use ultimate reality as an argument against God, they would.
Rather than defend people for using straw men, why don't you correct them? If you are really trying to help, why are you arguing with me in front of them instead of PMing me?
The atheist professes the position that they don't believe in truth. If they are offended at this reality, it is because even they know this is stupid, and they should abandon this superstitious identity.
There is at least One God we should all be able to agree on. The Truth. If you can't accept this God, you condemn yourself.
