There certainly is a large difference in culture, and it's evident in how we hold discussions and present ideas and feedback to the devs. Of course, that isn't to say that JP users aren't without their bad eggs or cringe-worthy moments, but I'm never surprised when I see someone give a sarcastic response to a team member's official response. Just disappointed.
From personal experience, I can say that presentation is everything. The last time someone asked me to pass a request along and gave me a sarcastic reply when doing so, I did as I promised and passed the request along -- but to repay the "favor" I was paid, I laced the request with so much sarcasm and dismissive language that my higher-ups literally laughed it off.
What I'm trying to say is, the devs aren't our flogging posts; they're content creators in what should be a mature environment, and we should start treating it as such.
