Free Speech Issues

Interesting analysis here of poll data over 1972-2016 querying whether speakers with specified views should be allowed to speak.  Americans seem to be supportive of free speech across the board, and have gotten generally more supportive over the period.  When divided by their political views, the more liberal people seem to be more supportive.  The writer sees this data as undermining the idea that liberal snowflakes are limiting free speech on campus.  I think that's stretching it a bit--too much variety in the U.S. and too much possible ambiguity in the definitions.  Still, it's interesting.
