Well, all I can really do is speak for my experience.
I’m a big fan of the New Testament’s teachings on loving your fellow humans, not judging others, forgiving others, and treating people the way you’d like to be treated. That said, there were a lot of people in my churches / fellowships that claimed to care about that stuff, but got so caught up in the other dogma that they ended loosing site of JC’s main teachings.
My motivations for non-belief are not driven by idolizing money or material things. I’m kind of a hippy and I distain people that overvalue that stuff. I simply of the belief that I don’t need to understand the afterlife in order to be a kind an empathetic human being. Life is hard, and since most of us have experienced hardship, we know what it’s like when other’s are suffering hardship. So we should try our best to love each other and help each other out.
I take offense to people judging me as a materialistic capitalist without taking the time to get to know me. I’m not happy with people that hoard wealth, I hate materialism, and I’ve spend the last decade volunteering my Saturday and Sunday working in recovery clinics to help my fellow man… because life is hard, and sometimes you need someone to help you out without casting judgment.
