I think that something in particular that Paul S. said got under your skin (and there was something he said that could certainly get under a person's skin). I'm pretty sure it isn't now a policy to rudely reject suggestions from people you haven't heard of! Until I went back through the thread I felt as Aahz did that your rejection was somewhat severe in tone. I think you (still) agree that people should not be afraid of (politely) stating their opinions in python-dev, even when those opinions disagree with yours. Or if there is an unspoken rule that unproven developers shouldn't be in python-dev then maybe we should just make it a spoken rule. But I'm most confident of the theory that you snapped at one person in particular because of something he said.
