Damaged emotions... rejection, trauma, or lack of love in early life
I'll grant you this one. It's entirely possible that some atheists began questioning their faith (if any) due to trauma.
Obliterated trust... no confidence in authority figures
Again, granted. However, it's not just "no confidence" it's "lack of confidence due to the evidence." Sorry, but when your religious leaders regularly live a life different than what they claim to believe, it does tend to make one question those beliefs.
Unrealistic expectations... faulty thinking about God and religion
Or rather, correct thinking. See, it's not enough for atheists (like myself) to accept what the pastor says god is like. We have to actually look in the bible, and see what it says he's like. When we do that, and compare that to reality, it does cause us to wonder.
Buried belief... no all-powerful God of love
You're right. Read your bible. God is neither all powerful (weakness vs. iron chariots, for example), nor all loving (willingness to consign people to an eternity of torture for mere disbelief)
Twisted truth... significance comes from what I do
Indeed it does. Interestingly enough, your Jesus seems to agree. Re-read that bit about the sheep and the goats. Who do you think the goats are referring to? Hint: It's not the unsaved.
Seared consciences... calloused to the touch of God
This would fall under the realm of not all powerful. If God truly desires that none should perish (see John 3:16), then why doesn't he do everything in his power to ensure that none perish? If my mind is calloused to his touch, then surely he can break through, being all powerful. If he's all loving, wouldn't he want to do so? Since he doesn't, we have to assume one of three things - either he isn't all powerful, he isn't all loving, or he isn't real.
