If I believe, and I do, that showing my opinions on stuff like this is right then. Is it about having enough people around me to make it feel worth it for me or a question of doing whats seems best to me? The sad truth is that most people who will probably demonstrate on this issue are those prone to demonstrate about stuff.
I have a feeling that getting up and actually doing stuff trying to influence what happens in society is a better option, for me at least. There was a mention of a ghandi saying earlier on the telly or radio something like "most things we do are insignificant, the point is not their significance but to keep doing them" (Edit: but it came out a lot better when he said it!")
