Ou, mais exatamente, "liberals", "conservatives" e liberdade de expressão.
Most liberals and smart people want racists to be allowed to speak, por Razib Khan:
Over the past year or so there have been many worries that liberals are backing off from their support for free speech. Even mainstream figures such as Howard Dean have started to chant the mantra “hate speech is not free speech”. And then you have op-eds from professors such as When ‘free speech’ becomes a political weapon.
But whenever I look at the General Social Survey I see no great change in support for free speech in terms of the patterns. Perhaps something has changed in the year 2017, but I think what we are seeing are vocal and motivated minorities who are drowning out liberal (in the classical sense) majorities. (...)
What the above plot shows is that liberals support free speech for both racists and Muslim radicals. Conservatives are more skeptical of free speech for both groups, but especially the Muslims. You might be curious why moderates seem so skeptical of free speech. That’s because on average moderates are less intelligent than people at the ideological poles, and the less intelligent are generally less supportive of heterodox speech
