If all the people who are so interested in protesting the next Olympics because they are in China, and China is the poster child of human rights abuses and tyranny over Tibet, such folk have no need to wait to huff out the fires of the Olympic flame as it makes a worldwide tour.
If you want to hit them where it hurts why not just boycott buying any Made In China products? That is, if you can identify them and learn to do without them for a while. (Good luck with that.)
In one case, a person's adventure with a 'year without China' led them to a create a best-selling book. Maybe you too can turn those protest signs into good ol' American dollars!
