" It is no defense of superstition and pseudoscience to say that it brings solace and comfort to people. If solace and comfort are how we judge the worth of something, then consider that tobacco brings solace and comfort to smokers; alcohol brings it to drinkers; drugs of all kinds bring it to addicts; the fall of cards and the run of horses bring it to gamblers; cruelty and violence bring it to sociopaths.
