“For members of the University community, as for the University itself, the proper response to ideas they find offensive, unwarranted and dangerous is not interference, obstruction, or suppression. It is, instead, to engage in robust counter-speech that challenges the merits of those ideas and exposes them for what they are.”
This quote is taken from the Chicago Statement on Principles of Free Expression, a statement whose values UNC has agreed with and affirmed. And, quite frankly, it is the perfect response to whomever placed this particular sticker here.
I would recommend to whoever placed this sticker that you read the Chicago statement in full. I have no doubts that your intentions are nothing but good – an attempt to leave the world in a better place than you found it. But it is a misguided attempt.
Your impulse to fight against the people and things that you find evil in society is understandable. However, the way that you go about such an effort matters. By refusing any public space to those who you might find offensive - or even merely disagree with - you engage in the very fascist tendencies that you claim to hate so much.
You might think that refusing a platform to those with offensive views is not fascist, so let me take you through the implications of such a policy. If it is acceptable to ban offensive people or views from a public space such as a college campus, what other areas should we ban them from? Social media is arguably such a public space - and has been banning offensive views for some time. So, perhaps, are newspapers or books - in similar fashion, the prohibition of sales of various goods (such as books) and services which promote sexual orientation change efforts has already been proposed in California. And if we reach a point where these areas are disallowed, a move to disallow offensive people from physically public places like parks does not seem too far off. Soon, you have segregated those who you might find offensive from the rest of society.
In short, the questions that such a policy raises make it clear that a view like this is undoubtedly fascist.
