"One very common tactic for enforcing political orthodoxies is to malign the character, "style" and even mental health of those who challenge them. The most extreme version of this was an old Soviet favorite: to declare political dissidents mentally ill and put them in hospitals. In the US, those who take even the tiniest steps outside of political convention are instantly decreed "crazy"..."
But what is at play here is this destructive dynamic that the more one dissents from political orthodoxies, the more personalized, style-focused and substance-free the attacks become. That's because once someone becomes sufficiently critical of establishment pieties, the goal is not merely to dispute their claims but to silence them. That's accomplished by demonizing the person on personality and style grounds to the point where huge numbers of people decide that nothing they say should even be considered, let alone accepted. It's a sorry and anti-intellectual tactic, to be sure, but a brutally effective one."
