Then vote third party, and when your friends tell you to vote for Hillary! explain to them exactly why you're not doing it: that she will do nothing to tear down the Bush/Obama surveillance state that went after people like Xi and Schwartz, and indeed will probably expand it.

Third parties do change things, even if it's just the major parties co-opting their positions after getting a scare in the election. "Hey, Party X took ten percent of the vote simply by opposing mass surveillance. Maybe we should get some of that action."
