I've found that people tend to talk about issues relevant to me (as an anarchist) on almost a daily basis. And, I've found that these conversations - whether it's one-on-one or in a group - can be rather frustrating... especially when it is decisions on things like where to eat or what to do. The frustration isn't because I'm an anarchist though, it stems from finding a lot of the ways people relate to me and others disagreeable and the urge to be "a bummer" or create conflict by passing off a comment about it. So I feel like it often comes down to a call of how seriously to take the things people say. When it's a serious discussion on politics or whatever, I've found my positions make it pretty damn easy to get along since I usually don't have to deal with a lot of presumption and can explain myself to a more open ear. Of course, if I just say "well fuck, blah - I'm an anarchist - grrr" that isn't at all tactful.
When my perspective on things seem to come up the most, it is usually in the context of sympathizing with someone's discontents and discussing them. Maybe I'll mention that I'm an anarchist; but, it's rare and I often find that sticking to the subject is my preferred interaction. I like to think that I'm an anarchist because of what my principals are, rather than my principals being determined by describing myself as an anarchist. This seems fundamental to the question being asked. The label isn't so important talking with friends or acquaintances in a social setting to me. It only becomes important if the conversation is specifically about political ideology or such topics where "anarchist" won't be the only label thrown around. I don't feel the need to ...represent myself as an anarchist in all places and all times: rather, I feel the need to be honest about my perspectives and socialize as much as anyone else (whether they're religious, conservative, punk rock, or whatever). So in a sense, I always feel like it is much more authentic/genuine/real to just express my opinion the same as I would concerning anything unrelated to anarchism.
At the interpersonal level, the goal is to treat people well for me... to treat them how they want to be treated (unless that conflicts with my principals). In short, relating mutually with others and avoiding those who a social manipulators, sexist, homophobic, etc. is more my concern. If I want to really talk about anarchism with someone, it isn't a personal conversation and I talk about it the same as I would talk about quantum physics theories and other abstract stuff. I don't use it as a way to get into arguments or separate myself. If someone is interested in learning about anarchism, I can become a bit excited and blabby but I do the same thing if someone is interested in learning about the social history of art or some other subject I'm passionate about. If there's an action or event or whatever... I'll invite people and if they don't think it's important that's their deal but I won't be shy if they ask why I think it's important.
I don't know - it's all contextual, but overall - 99% of the time I'm not interacting with someone with anarchism in mind. I'm probably more worried about how they've been, what they're doing with their lives, having fun, etc.
