I've had the same experience with a stuttering support group. I also tend to avoid people with more moderate or mild stuttering, or people who used to stutter. Here's why I think this is the case. I find that people with mild stutters, contrary to what you might expect, tend to be more judgemental of stuttering than fluent speakers. I think it's because they _think_ they _know_ stuttering. They think they've "beaten" it through one method or another. Then they come across someone who stutters badly, and they assume that--due to the fact that they themselves "beat" their stutter through hard work, or growing out of it, or developing their confidence, etc--_you_ the bad stutterer must not be trying, must not be in speech therapy, must not care about your speech. They don't mean bad, obviously. But interacting with them infuriates me so much that I just avoid it. I've been through so much with my speech. I don't need someone suggesting I "try speech therapy" or something other thing that I've already tried.
