Seeing that thread just reminds me of my poor form lately, no decent internet arguments for several months
I feel I could make some pretty valid points about the discussion, but they have probably already been made... So I'll leave you with this:
In many 'community's' or 'scenes' or whatever you want to call them, these exact issues arise all the time, I can think of dozens of examples off the top of my head.
I think a lot of people are trying to reach a middle ground between an exclusive and controlled circumstance (where those on the outside despise those on the inside) or a public free for all (where rifts occur due to the different behaviour and attitude of those involved)
I say forget about the middle ground, its not going to happen, and when it does the same issues will just come around anyway.
Make the most of the public free for all, it serves its purpose...and if you can try to set up your own exclusive circumstance or get involved in one, then you can forget about all the bullshit and just get on with it.
If that made no sense then that is just unlucky, but its the truth.
