i recently read a book by jonathan hite he was a uva professor now at nyu.i heard nadine strossen who was a former president at aclu who speak your time recently. mentioned what, there is an organization the heterodox academy and essentially it was, my understanding is what jonathan, professor liberal and nadine, also professor has said is that from the '60s in academic world, two out of three professors would be classified as to the left. today at somewhere around 20 to one. their concern is the ability of students to engage in critical discussion and free speech and what the effect has been on the academic community and wanted to get the thoughts of the panel on that. >> i actually don't think the students are facing many barriers to critical discussion of freedom of speech. i think by large universities face problems on the edges by large, in classrooms and and student groups, students are engaging in really fundamentally they conversations in universities. i think that's a bit of a red herring, but i do agree that universities have changed substantially.
