This normally goes without saying, and is something I think most of us were taught at a very young age:
You vote by secret ballot and you reserve the right to keep your vote secret. You are under no obligation to anyone to answer any questions about how you vote or plan to vote or not vote.
I guess it's good that people are becoming politically active, even though it's sort of a circus. But the stuff I've been reading/seeing becoming socially acceptable behavior - is intimidation.
