They survive often not due to correctness or applicability, but rather according to traits which enable reproduction.
Consider an ideology that preaches to its followers "be fruitfuil and multiply" versus one that preaches celibacy.
The population of the first ideology will grow faster.
However, the rate will be cancerous, and the ideology will run the risk of self-contamination through misinterpretation. Everyone will fuck like bunnies to the extent that there is no central authority on what's what and the ideology dissolves into schisms.
Meanwhile a smaller-population ideolgy might thrive and survive under these conditions if on its toes, scattered, and deeply rooted in its own dogma/intelligentsia. If the average adherent knows a lot about the ideology and its enforcement and the nuances of survival, it might not matter so much of the followers are churning out kids.
Because most people do not understand the principles upon which their ideology thrives, but rather only the principles upon which their ideology is based, proponents of ideology are highly susceptible to MAD BAIT and WICKED BUTTHURT and can in fact be confused into hurting their own ideology much like POKEMON.
It thus necessitates that in order to be safe the True Individual™ must inoculate his or herself of any and all ideology, particularly the most dangerous ideology of all: The ideology of the True Individual© who confuses oneself into thinking they are without ideology when in fact they are the most deluded of all.
As this is not possible, the circumstances necessitate physical removal

Ideologies don't filter based upon their philosophy, but on their ultimate geopolitical success.
Eventually, any ideology that gains success will weaken as it is distilles into the general population and is normalised, becoming another layer of tissue in the identity of those who live within it and nothing more.
