I've gone to a few political rallies and inevitably find them dismaying. There are a variety of reasons for this but a couple of obvious ones are that I find myself in a group of people, some of whom are expressing nonsense and because it requires - rather than challenges - conformity of thought.
The exercise of writing a blog post, by contrast, forces me to articulate thoughts that are not always clear or coherent when I begin but I have feelings about - a process that seems the reverse of protest marches. A blog post also forces me to articulate a position that is individual (what is the use of quoting - at length - someone else?) rather than fit in with a group that - at best - loosely maps to my own beliefs and sensibilities.
