I would say you are mistaken in the belief that these policies exist because of certain leaders. In my opinion, they exist because the electorate is misguided in believing that this kind of 'censorship' is a good idea. Therefore, I would suggest that voting out the incumbent will not necessarily make the problem go away. I believe that the best way to deal with this is by spreading the counter message to show just how foolish and misguided the policies are. In addition, you should write to your government representative and let them know how you feel, ideally providing some good justifications for your argument.
