I'm not at all, I just think that kind of mindset can create a barrier between a select group of "oldguard" and the rest of the members, which is a barrier that is hard/impossible to break through. I've experienced this in a lot of internet groups I've become a part of, and it's been a major factor in me leaving in at least one of them.
You are right, I think in terms of the social aspect, and risking being shut out by doing something deemed unacceptable, those who have spent years on here would be much less likely to do such a thing. On the other hand, some people just don't care what others think, which can be both good and bad.
While this community is a lot more accepting of people than others I have been a part of before, and the distinction is more a case of knowledge rather than "skill", I think we should be wary of providing special treatment.
