Hah, my apologies - I jump at any chance I get to explain why nebulous, unenforceable, or even impossible laws can nevertheless have concrete and worthwhile benefits, it’s a favorite pet topic for me.
No need for apologies, I saw no good reason to take your comment as combative or dismissive or anything!
Fun. Now do "why voting for an unelectable minor party can still change the world", I like that one.
Tall order. I guess I could cheat and say “it might change YOUR world”, insofar as it can put you into a like-minded and passionate community?
Yes, and then you're influencing a passionate community by telling them all about how you voted, with sincere passion. But the other relevant effect is that a minor popular movement will give their minor party some votes, which then causes concern to the major parties - or looks like an opportunity - and makes them steal the minor party's policies in some form.
