That is a valid and serious concern. I’ve come to think standards need to be factual and not ideological although that is the first claim of anyone who’s ox has been gored. The answer will ultimately be objective and AI based but in the interim it needs to be flagging of blatant falsehoods. This cannot be censorship blocking access to opinion but indicators if opinion is predicated on lies or factual inaccuracies.
The reality, as most people realize, is that the cause of much of the political and social damage are coming from the descendants of Conservative tradition who have abandoned fact and knowledge in favor of fear and ignorance.
I have no problem with rational arguments against democracy, public education, and public health if that is the position taken in public debate. The social goals of that and the justifications for them need to be articulated. Obviously the majority believe that free public education and the ability to avoid disease and early death are important. We have a minority government that doesn’t seem to consider those important goals for anyone without significant family wealth or a very well paid position but they are trying to hide their goals.
The reaction of Facebook and Google to the problems they facilitated by Actively censoring false information is already being attacked as ideological because the use of falsehoods is most prevalent in the Republican agenda. Their ox is quickly going to bleed to death. So be it. Ideological orientation should be irrelevant.
