If factual information upsets you, then you are creating a world that is not embracing objective truths, and that's not how you advance a democracy.
Knowledge of the natural world and how it works should be counted as fundamental to informed governance. You can't have a functioning democracy, if the electorate is under-informed or, worse, mis-informed.

When everyone agrees to a single solution and a single plan, there's nothing more efficient in the world than an efficient democracy.
