Rambamist Elitism

Why do Rambamists write so many posts about how other Jewish people are basically idolators?

What does this actually accomplish?

Is it possible that to whatever extent Rambam may have been something somewhat approaching a philosophical elitist, emulating that tendency may not actually be productive towards promoting Torah, or in the cases of most people who aren’t Rambam, even warranted?

* Asking as someone who believes that the Mishne Tora is the best guide to halakha and that philosophy is the key to understanding the Torah and having a real relationship with the Creator, and who prays according to siddur haRambam.
