How can we better deal with right wingers and conspiracy theorists who are trying to politicize COVID and use fear-mongering to popularize their conspiracy theories during a pandemic?

This is especially true on social media and sites like 4chan, we we have a large number of people trying to use the platform to engage in disinformation and to bully other users into being fearful of the scientific and media establishment. These people are ignorant retards and they don't care about anyone but themselves, and people are perfectly happy to allow them to spread their narrative, because muh rights and muh freedumbs cannot be infringed.
