i dont think tthat striving for 'utopia' and idealism puts people off just because it often results in ignoring practicality for the sake of perfection, but because it turns a conversation that should be about treatments and solutions into proselytism
most people flat out are not interested in learning the theory of whatever ideology youre trying to sell them, and therefore will not be interested in whatever treatments and solutions youre proposing for individual problems as part of that ideology
focus on educating folks about the actual problems and pointing them in the way of the individual solutions to those problems
