There are many movements which would benefit from more rationality. But there are also many movements which would be harmed by more rationality. I wonder whether the latter have already formed a silent coalition...
My friends have a proverb: "The easiest way to recognize an intelligent person is that in the moment they enter the room, all the idiots instinctively join against them." And it often seems to work (possible selection bias here).
I can imagine that when a person enjoys something irrational (horoscopes, some political movement, etc.) and they often get opposed rationally, it may condition them to hate anything that sounds too rational. Later when they hear someone using rational arguments, even if it is completely unrelated to their favourite cause, they get angry.
That's a sure sign that your friends aren't very bright. Charisma is itself a learned skill, and intelligent people very often possess it. While it is not a sure sign of intelligence, if everyone doesn't like you, then you're in trouble.
"All the idiots" is a pretty arbitrary term, and it is also really questionable - how do you define idiots, then? As those who disagree with you?
Manipulating idiots is actually generally easier than manipulating average people, and idiots are not any sort of single group - low-functioning persons often fight amongst themselves.

This post is part of the Rerunning the Sequences series, where we'll be going through Eliezer Yudkowsky's old posts in order so that people who are interested can (re-)read and discuss them. The previous post was Church vs. Taskforce, and you can use the sequence_reruns tag or rss feed to follow the rest of the series.
Sequence reruns are a community-driven effort. You can participate by re-reading the sequence post, discussing it here, posting the next day's sequence reruns post, or summarizing forthcoming articles on the wiki.
