To be fair, that's part of the nature of an internet forum. I think a lot of people take their filter off or turn it down a few notches when it comes to expressing their views.Sam openly debases people for believing and their faith specifically.
I'm pretty sure if we were all out for drinks, we wouldn't be debating the nature of god, arguing over Amby letters, or politics. In contrast, discussing these things are an almost daily occurrence (because it gives us something to discuss and take a stance on, talk about, and receive feedback and different perspectives), however IRL with friends and associates, I almost never get in passionate debates about these things. When it comes to religion, at most I may say, I'm agnostic and that is something I generally only share with close friends and my immediate family. Except for those I am very close with, I don't share my intimate thoughts on many issues discussed. I tend to do that more so on here.
You all are my sounding board sometimes. IRL, I'm much more introspective when it comes to these things and I want to have fun, not argue when around people.
I presume Sam and many others are no different on here.
I think Tonka quite a long time ago touched on this.
