It does seem a bit odd. Did they every clarify what it is specifically about your particular involvement that is problematic? I'm left wondering if you posed some kind of new threat and triggered some fear. I hope they can work out the source of that fear. Either way, I feel for you. Do this long enough, and these experiences happen.
And...I don't think these reactions make people inherently "good" or "bad." We are all in different places in our journey and along the way we are bound to fuck up from time to time. I wouldn't categorically write them off as being somehow "less than." They just aren't where you need them to be for your own health.
