What can we do?

I've been a lurker here for a while now, but I'm becoming increasingly concerned about the way things are going in the US. I'm not American and have no desire to be so, but it seems that the sort of politics they're swinging towards is really catching on in other parts of the world. Unfortunately, the UK is included in that. <br><br>So that's the problem, what can we do? I want to make some changes, but I've never been a fan of protests. How many do we need to have before things change? I've been to my fair share but I don't feel like they achieve anything. Does anyone have any ideas on what we can do?
