Only one of those questions pertains to the actual application of the First Amendment and its content, which was "Does the First Amendment protect hate speech?" On that question, the political divide between Democrats and Republicans is almost statistically insignificant (a mere 5%). I suspect the cause of this stems from ongoing debate concerning whether the First Amendment protects hate speech or not; there are some voices that support the perspective that it shouldn't. So, I suspect there is a confusion over should and does.
The other three questions do not concern themselves with the legal application of the First Amendment, but whether or not college students support an environment conducive to speech from potentially unsavory perspectives and voices. Why should a person such as Milo be allowed, not from a legal perspective, but rather from a social one, to speak freely and spew hate? Yes, it is perfectly acceptable to shout down such speakers and, in certain circumstances, violence may even be acceptable. Fascism should never be tolerated. Although we cannot suppress it legally, we can socially.
