@izzythepush,
I support free speech for all. I would be just as upset seeing a speaker supporting the Muslim Brotherhood, or the head or PETA or any other group. If there is a group of students who invite a speaker, the speaker should be allowed to speak.
Free Speech protects speech that is offensive or unpopular; the same laws that protected abolitionists, and early proponents of same sex marriage, and anti-war speakers (all of these are viewpoints that have been both unpopular and offensive)... now protect the Alt-Right, Islamicists and both sides of the Israel debate.
The problem currently is that the political left is doing the censoring. I haven't heard of any leftist speaker being banned from campus.
Free Speech is Free Speech. I support it as a basic right for everyone, whether I agree with their ideology or not.
