The most effective cluster of memes are the ones that are most truely in tune with genetic human nature, and, of course, the trojan horse for "getting in" are those memes that we are most familiar with at this moment in time.
So the "Meme War" is for the rapidly evolving cluster of memes that are in best harmony with the present state of human nature. There is something about Christianity, Islam, and Hinduism that has keyed in to those elements; that have caused them to be so effective; that elicit strong emotions (human nature confuses emotions for evidence of truth.)
The only evidence of truth that these superclusters of memes (religion, tradition, social behavior) will reveal is the architecture of the human psyche, and their success reveals little or says nothing about the laws of nature or the nature of the Cosmos.
But they are powerful enough to destroy and displace other modes of thinking. Civilization is in peril due to these memeplexes, especially the one that believe eternal economic "growth" is a good thing (as if cancer is good) and that to not grow, is to die. I would go with "to not change invites memeplexes to break down the immune system of civilization."
