Don't know much about what goes on on campus. But I gather college age folks are turned off to politics. Many don't care about losing democracy long as they have a "good job".  Maybe that's why they don't care about free speech. They're willing to be a silent compliant corporate drone if the pay is good and they have some power.

  But they're certainly not my idea of left wingers. Neither are feminists pro-LGBT, or pro- Islam fanatics who aren't foremost working to revolutionize the rigged economy and transform the corrupt political system.
  
  In the US Bernie Sanders is the most popular politician of university students. Bernie's policies, goals and attitudes make complete good sense. In  my opinion, Bernie is the quintessential, genuine left winger.
Has been for 50 years and still is. And Bernie loves free speech. 
 
If university is about "social work" it's no wonder the power structure is more oppressive, economy more unequal, politics more corrupt, university more expensive.
