I'm not sure I'm convinced that taking away anonymity fixes the problem. We have very prominent politicians who are driving entire political campaigns around this strategy of ignoring all fact.
I honestly think that prominent politicians wouldn't have any willingness to adopt this insane level of misinformation if there wasn't such a general societal acceptance of it.
The people in congress that believe in jewish space lasers didn't get elected because everyone around them thought they were crazy conspiracy theorists.
