What happens when people with the opposite political views (Bolsonaro, for example) come to power and label you the extremist that no longer is allowed access to a platform to spread your message?
Just trying to point out that this is the same language and reasoning that, for example, the neofascist regime of Argentina from 1976-1984 used in order to pacify the public for the disappearance and torture of 30,000 people, mostly leftists.
