I'm not exactly sure what you're talking about. I've been in their irc channel for hours at a time, and all the community seems to be doing is helping people with their javascript noob questions, even if they aren't related to Mootools.
The documentation is rather straightforward as well. It's pretty easy to figure out what something does.
Perhaps your contempt is outdated?

I agree about the condescension part, which is very unfortunate knowing the immense potential Mootools had when it was still called moo.fx. In fact I believe it could have reached as wide an audience as jQuery, if the community was more friendly.
What's seriously better? MIT License maybe.
I made the switch about a year ago and haven't looked back since.
