|Welcome to the Monastery|
Xerox PARC OO isn't Moose and Moose isn't Xerox PARC OO. So both sides of your interactions might be perceiving or suspecting some idiocy due to significant differences in expectations when talking "OO".
As for the "haughty", your name dropping makes me suspect that might also be something being perceived/suspected on both sides of your interactions.
(No, I am not trying to claim that there is no "haughty" nor "idiocy" within some subcult of Moose that you have been interacting with. I actually expect to find a higher quotient of Kool-Aid among Moose officiandos than within the wider Perl community -- though a lower quotient than, say, among Perl::Critic fandom.)
I recall Larry commenting about not being so rude to newbies and that mostly being in line with more extensive such comments from Casey
If Larry's comments were significantly more recent than that (as your description clearly claims), then I would guess it was in response to Perl6-related knee-jerk responses that have been evolving into rather nasty trolling. So I doubt that has much to do with your Moose woes.
Vague and over-broad problem statements often don't lead to answers that address the problem well. I can understand your reluctance to just call out who was rude to you where, when, and how. Actually, I discourage you from doing that. If you can muster the eloquence, then some particulars about "where" might get you better-targeted answers without earning you much pay-back, though.
