Obvious as it may sound, people with authoritarian beliefs hiding behind free speech actually consider it as a weakness akin empathy. It allows losers like them to amplify their reach despite not being in power. They abandon their “free speech absolutist” postures the moment they think they are in power.
It’s important for everybody to not just assume the people on your own team, or the people that look like you, are being truthful and arguing in good faith.
That goes for everybody, but it seems pretty consistent that you need to me more wary of it as you move towards the conservative end of the scale. And conveniently for those politicians, the citizens on that end of the scale are the worst at cutting through the BS. Arguably that’s what landed them there in the first place!
