Re: Why do you not pray?
I had a quick look at it as well as the other link you provided. I saw no connection made between religion and lack of peace. Also, as per the second link it seems that they’re only basing their stats on how many people describe themselves as religious or not.
So that doesn’t really show a connection between atheism and altruism. From what I’ve seen growing up in Canada, the level of religiousness among Muslims has increased over the years. This has not been linked with increasing levels of trouble and has not had any adverse effect on the level of peace here. Muslims have been targeted by politicians for their own ends but there hasn’t been any decrease in peace due to their becoming more practicing.
