@BenRossTransit @djc That's the kind of thing I thought you were talking about! And that's where we have a dispute about prevalence.
Media and social media pluck conflict from the tails of social phenomena, because that's where the engaging stories are. Ridiculously horrible slogans definitely are shouted, and sometimes in harassing ways at Jewish students. There are also purposeful provocateurs on the pro-Israel side.
But I think these both are a very small part of the overall activity.
