You refer to your "principles," blankflag, but the thing is, even if you have principles, it's unlikely that you have to talk about them all the time. Sometimes it's possible to come across as so obsessed with one subject that you're just a bore to other people, and they don't want to be around you, because, even if you might be fun if you would shut up about it, you won't.
This is a mistake. If the government is really trying to control all our lives down to minute details, and deceiving us a lot (for example), that is absolutely something we should talk about and try to do something about; but it's still not something we should talk about to the exclusion of everything else -- only when it's going to be productive. When you go to a friend's party, for example, you're probably not going to achieve anything productive about the situation by talking about it, whereas you _could_ have a good time with your friends, so that is probably a good time and place to just do the latter. But some people don't. The irony is that the whole reason to worry about the government being oppressive is that it would prevent people from being able to pursue the things they want and value in life; but a lot of people worry so much about the government's oncoming oppression that they voluntarily stop pursuing those things of their own accord.
I'm not saying that's necessarily your problem. I don't know you in real life, so I can't say. But I've known people a little like that, and I could *imagine* it being your problem; and anyway it analogizes, somewhat, to other things. The point, again, is not to stop acting about the things that trouble you, but to understand which of your actions might have a good impact, and which are just costing you personally without achieving a thing.
