I am envisaging a platform that allows the community to structure and "type-check" (loosely) arguments.
The key I feel is to allow people to post as they normally would and then allow annotation tools to structure arguments. Essentially a super easy UX to carry out [argument mapping](https://en.wikipedia.org/wiki/Argument_map).
The goal would be to find as much as possible that people agree on (definitions, evidence) and then to focus the arguments on the specific points of contention.
I can imagine a template of logical argument forms such a "X should do Y when Z" which would need to be filled in for an argument to be valid.
Its usually difficult to come to an objective truth when arguing, so another key point is tracking consistency of argument. This is a great way to invalidate an argument. If someone makes a claim like "X should do Y when Z", if they are caught saying "X should not do Y when something similar to Z" then its a great way to invalidate an argument and unearth bias without having to examine the rest of the argument.
I want to bring back the art of debate!
