So if, for example, I support some position (let's say, anti-abortion) based on my religion, and someone responds with information about why my religion is bunk because of depositional layering... what's the expectation for a response? Is it my job to suddenly research and understand such data? How could I judge otherwise? What if I had tickets to a ball game that I wanted to go to instead?
It's not entirely clear what's being asked.
If you believe "anti-abortion", that's fine with me. Just don't have any abortion. There isn't a problem unless you attempt to impose your belief on others.
