Yes, I support free speech, however this kind of feels like a loaded question, and I believe there will be some who vote for "yes" in this poll but retract and call "hate speech" when presented with certain offensive ideas/discourse. Denying the right to free speech doesn't just consist of outright saying that free speech should not be allowed. It also includes narrowing down the scope of free speech to "safe, allowable ideas", and labeling nonconforming ideas as hate speech.
Also on that note, it's quite disturbing that you had to clear yourself of any "alt-right wrongdoing" when you were simply talking about free speech.
