If we're going to take a middle of the road POV, let's get a few things out of the way.
For one thing you're failing to acknowledge that this gay, British/Greek (immigrant) is the same person who has been banned by twitter for racist & misogynistic attacks, outspoken harsh critic of homosexuality/rights & happens to be the senior editor of the, to put it mildly, far right Breitbart who's been pretty instrumental in defining the alt-right movement and this speaking tour has been a continuation of much of that ideology. Important context because many see this as hate speech & not just free speech....hence the protests.
A second important thing to acknowledge is that while the crowd was likely mostly students what has often been happening at these protests is that small groups of people use these protests as cover to commit violence and that's their sole motive for being there. This is something that has been happening in the
US and Europe. These are public protests that anyone can attend & are often planned on social media for all to see. Do other normally peaceful protesters take part or incite violence & destruction? entirely possible....welcome to the mob mentality.
Should this gay, British/Greek (immigrant)'s possibly hate speech be respected or protected by the protesters? IDK if I'd go that far.
Either way it is the ultimate troll.
