I get that, and I agree. As I've said this is something I've been reading about for quite a while and gave up because answers were not forthcoming. IME you can debate with nazis, I've scored two minor conversions over the years. I believe converting people away from IS would be still harder, but someone may one day find a way.
So yes, I change my mind. Maybe it's not a waste of time to learn, but don't approach it looking for a way to engage and argue rationally because my experience is that arguments are irrelevant in this matter. What God wants will always win, because it's what God wants. God decides when to punish and show compassion, and holy men are not to be argued with on pain of death. It's hard to even appreciate the utter absolutism, because most if not all of us have grown up in an environment where you're always allowed to question, at times even to disobey.
Also, afterlife. That's a whole nother angle. When you die you don't really die. I know a lot of people have this idea but not all of them act on it by killing themselves to get there quicker.
