You're absolutely right. I have seen this sort of attitude from quite a few domain experts - if you didn't get it, you aren't smart enough and "don't deserve to be in our group".
It's very sad because this is exactly the perfect feedback to know what the heck is wrong with your approach. We collect feedback for the tools that we put up on the web - these are usually non-technical people but people around me always dismisses it as "they aren't smart enough to get it" which annoys the hell out of me. Making things easy to understand and easy to use is what drives adoption rates. It's what made Apple the dominant. Sometimes handholding is necessary until knowledge has been successfully transferred over.
