tl;dr how muslims turned christians into a declining minority in the middle east and how pagans or atheists can do the same. to be altruistic, to help the meek and poor, is to be virtuous especially in christianity. tthis video demonstrates that in group population dynamics, altruism is a losing strategy that results in the extinction of the altruistic group. the only case where altuism is a successful survival strategy is when the altruistic group can identify each other and help each other exclusively (in-group preference).   g at the end of the video is a simplified simulation that involves 4 phenotypes. 1. "the cowards", who don't help anyone 2. "the suckers", who help but are less likely to receive help 3. "the true beards", who help conditionally (if the other blob has a green beard) 4. "the impostors", who do not help but are likely to receive help (who are not altruists but have a beard) some real life analogies can be drawn from these as archetypes. 1. "the suckers" are christians or christian apostates (atheists) who retain atruism as a moral, but do not receive assistance in return.  2. "the cowards" represent anyone who doesn't participate in charity, neither as a donor or recipient. 3. "the green beards" are muslims or jews. these religions teach their followers to be charitable but only to other members of the faith or tribe. 4. "the imposters" are jews, who are sometimes white and sometimes not depending on political climate and when it's convenient, or anyone who has managed to grift donations despite being inauthentic in beliefs or heritage.
