Right so you think they should be barred on their opinions, which is why I disagree with you. Obviously you should make dictators illegal in your constitution, which should be democratically free to be revoked and modified. But that is not the same as saying that you should bar a politician from office simply for WANTING to be a dictator. In that case we just shouldnt elect them.
Thought policing is about as fascist as you can get.. blocking people because of their **opinions** from the right to a fair and free election is just a horrible idea.
