Because no one is listening. Polarization is increasing in America– see this Pew study.
Why is the US becoming so polarized? In three words…the second law…aka entropy. Or to be more precise, dis-equilibriation. So while Jon Haidt’s noble oratory is impressive and moving, forcing conservative ideology onto resentful campus communities is pretty useless.
The only interesting part of this exercise for me is the difference between what conservatives and liberals are willing to accept/excuse in their standard bearers– conservatives accepted Trump’s “pussy grabbing”– will they also accept/excuse Milo’s “soft pedophilia”/man-boy love? While I know many liberals from my cohort that voted for Gary Johnson (a geographic ignoramus unaware of the location of Aleppo) because they viewed HRC as a liar.
My hypoth is that in the EEA two distinct and equally successful phenotypes emerged– an expression of the Cooperation Competition Paradigm of Complexity Science. Let’s call them explorers and soldiers. The equilibrium between the two sub-populations ensured in part the success of h. sapiens sapiens. But in the 21st century the relative parity of fitness of the sub-populations is eroding under globalization and technology. What happens to Jefferson’s Noble Yeomen Farmers is the huge problem going forward. Academe is +90% liberal…the military is +90% conservative– these are evolved institutions. Academe selects for upper tail of IQ and g— military selects for obedience, loyalty and bravery– eg, entrance to the military is 90 IQ points. Explorers and soldiers. But going forward soldiers will be the first to have their jobs automated. Indeed, the non-college part of the american workforce will lose their jobs to the robots first as well.
In the recent presidential election conservatives captured the presidency in spite of losing the popular vote– Trump won by less than 100k votes in four battleground states. But unless conservatives can capture academe and culture the pendulum will swing back…that is the way the Founders designed the system– its WAI. Thus Trump’s attacks on the press, on universities, on science, and on celebrities are attempts to recapture the organs of culture and academe. Academe and culture can change youth with conservative genetic tendency and conservative parents into liberals. Consider the scholastic poll from 2016– ever shrinking jesusland.
So free speech is just a stalking horse for conservative exclusion from academe. And forcing conservative ideology onto campuses wont make any difference in the widening gap. America needs to be honest about the problems facing our country. The truth is, conservative ideology is not competitive at universities, or in Hollywood. If the correlation of educational attainment and liberal voting patterns holds, along with the progress of the demographic timer, there will eventually be a liberal supermajority– the pendulum wont swing back. And that is probably not a good thing for a democratic republic.
