"hey matt, sorry if the question irritated you."
There's no need to apologize. I wasn't irritated, I was just trying to provide a direct answer to a direct question.
"since you say that a community can easily become a subculture, isn't it also possible that a subculture can become a community, and that both change?"
It's certainly possible, I just think that, in most cases, it's not all that likely. Then again, maybe the anarchists that I used to hang out with were the wrong anarchists and my perception of the likelihood that a 'community' can emerge out of a 'subculture' is coloured by those negative experiences. If you've found a solid crew of people with whom you feel that you can have interesting conversations, engage in projects that you think are worthwhile, and not cloister yourselves up in your own little echo chamber, then I think that's great. I just have my suspicions that this is probably the exception rather than the rule.
"also, you have pushed the button in me that gets irritated when people talk shit about anarchists in a shortcut way."
From my perspective, I'm not "talking shit about anarchists," I'm just talking shit about the tendency of many anarchists to hole up in their respective subcultural bubbles and reinforce one another's prejudices. If you maintain an active awareness of this tendency toward subcultural insularity and are taking steps to push back against it, then I see no major problem. But, as I said in my answer to the original question, it's also easy to get complacent and think you're pushing back against this tendency when, in fact, you've just gotten too comfortable in your local scene. I'm not saying that this is what you've done, but that I suspect it's a pattern many well-intentioned anarchists have unwittingly fallen into.
