Do you think there is a chance of world peacefull coexistance ?
Not as long as there is religion.

Luckily, the day will come when the last religious person dies.
This answer is so good. Sadly, those persons are mostly from the older generations right now, therefore we're actually hoping against some of our relatives, maybe even parents.
The minds of the older generations, too many times, are hateful though. Hateful against gays, against other religions, against immigrants, and so on.
