I have been pondering my recent episode of blocking/stopping traffic during the Not in Our Name Rally. It is a tactic that many protestors do not agree with,I know. There are tactics that I do not agree with as well. We all do what we have to do.
Some people ask what it accomplishes, besides "pissing motorists off". In truth, it is not my intention to piss anyone off. In fact, I am not attached to their response. I am simply doing what I feel I need to be doing. I am making a plea for peace.
When someone is trying to "sell" an idea they often "advertise" it. Since so many people spend so much time in front of their television, taking out an ad would be a great idea, but not a practical one financially.
So standing in the street in oncoming traffic is a way to get people to stop and pay attention to a message, to an "advertisement". They may indeed get upset or excited (effective advertising does cause arousal) but they do see and will recall the message.
