You can't really be forced to believe anything. You can be threatened to and lie that you do and follow all the rituals and repeat the sayings, but that doesn't mean that you will ever come to actually believe it.
Kasic, this is hypothetical. We are assuming that it is impossible to be atheist, so therefore you cannot be forced to have a religion, you would always have one of you choice.
Mine would be Judaism, mainly because I am already Jewish
I'd pick Buddhism. You get to become a Shaolin monk and kick major a**.
But what's the confusion here? It's strictly a scenario and he's saying if you had to pick any religion from the 7000 there are, which one would you pick?
I would become Buddhist. I like the concept of reincarnation and Karma. Also you don't have to be a member of that religion to get rewarded in your next life unlike in some other religions. That seems much fairer to me than get punished for not believing. Another plus is that Buddhism is one of the most peaceful religions.
