We really live in the age of head-in-sand. How do you do anything about that? Somehow reality has become not just optional and uncertain in our policies, perceptions and opinions, but downright irrelevant. When there's no merit in even trying to be truthful and accurate, well... you get this.
Dismissing facts as lies is just... something to say. Bolsonaro and his followers know this is true but they simply don't care. Which is a reasonable political stance I reckon.
Run that by me again.
How is denying something you know to be true a reasonable stance.
How is taking (or actively not taking) a course of action you know will harm the people you've been elected to serve, a reasonable stance.
This is pretty basic stuff for a democratically elected official.
