It's much harder to articulate a coherent point of view. Contrary to what some people think, others' perceptions of activists' tactics do matter. The unfortunate thing is, respectful dialogue could have actually had an effect. Protests like the one that went on outside the chapel are powerful and can get their point across. Question and answer periods were also invented for a reason.
Protests are extremely important.
Protesters, as a historical entity, have often been willing to say what others were too frightened or indifferent to say and put their very lives at stake doing so, for the better of all of us. But education is important too, and so is informed voting. Perhaps most important is that we consistently examine ourselves and our politics, so that we can become more informed and active citizens. Not only did the protesters in the chapel refuse to engage themselves in the issue, but they prevented others from doing so. It's easy to get stuck in the same old routine here.
