Yeah, don't do anything? Why do we have to do anything about """disinformation"""? What'll happen in a few years when the things you stand for and believe in are labelled as disinformation? Because if you start censoring and combating "disinformation" now, it's only a matter of time until the same practices start affecting you and the things you stand for.
Besides, do you really think banning people off of platforms for wrongthink is more likely to make them change their minds? If anything, those kinds of actions cause resentment to fester, which only leads to more radicalization (for lack of a better term) in the future.
