The premise is fine. I've seen sites like this before. However, if you want to invoke honest discussion and change, there should be a way to invoke nuance into the questions like "Should abortion be allowed?" By having a sliding scale (1-10), you have indications of that but not the information of why it's not a binary decision. Same with gun ownership and other questions - while you say it's a voting site allowing for nuance, there isn't feedback on why it is beyond a Positive-Negative graph where we would start at neutral.
