The concept of the "safe space" is basically just bullshit activist newspeak for "place where I never have to hear anything I disagree with." To my understanding, the concept of "safety" within radical activist/anarchist subcultures does not typically pertain to *physical* safety so much as the safety of one's worldview from any sort of cognitive dissonance.
While I appreciate ingrate's desire to not see anyone at anarchist gatherings act as "judge and jury" toward anyone they disagree with, I am skeptical of any organizational 'model' that attempts to accomplish this. Regardless of whether one's desire is to *maintain* a safe space or call it into question, organizational models that attempt to enforce or otherwise facilitate a particular vision of 'normality' within the anarchist scene are ultimately opposite sides of the same coin. The incident at the Seattle Anarchist Book Fair involving the Atassa Journal a few months ago is a clear illustration of this fact.
The person who confronted the folks at the LBC table could be seen as either *defending* or *undermining* the idea of a "safe space" depending on how you want to look at it. Granted, you could say that they were undermining it because they chose to adopt a physically confrontational approach, and you wouldn't be entirely wrong for saying this. But, at the same time, this person could just as easily justify their actions by saying that they were *defending* the safe space by attempting to prevent the violent rhetoric within the Atassa Journal from being circulated. I'm not saying that I agree with either perspective, just that one and the same action can be seen as serving opposite motivations.
The most sensible response to all this is not, in my opinion, to adopt a new organizational model for mitigating conflict within the anarchist subculture but to start exploring ways to *break out* of the subculture itself. If book fairs, for instance, have become toxic environments in which the people who want to preserve their ideological echo chamber are constantly doing battle with those who want to challenge it, then book fairs have outlived their usefulness need to stop taking place. Don't get me wrong, if some people enjoy that sort of drama and want to continue participating in it, then that is their choice. But for those of us who are fed up with it, it may be time to just sever ties and move on.
The anarchist subculture is its own worst enemy. It's time to start thinking creatively about how to burst the subcultural bubble and relate with each other as individuals.
