I was in grad school at Yale during the latter years of the Occupy protests. Some undergrads set up some tents in the Occupy space on the New Haven Green, which abuts part of campus. I was walking to class one day and I noticed the tents and the signs and they Yale protesters. I thought the entire protest was stupid, but I remarked to a colleague that I respected them for being out there in the snow and ice and cold (Connecticut in the winter) overnight. As an Army veteran approaching his 40s who spent plenty of time outdoors in the cold (thanks Korea and Afghanistan!), I wouldn't do it, even if I believed in the Occupy cause... which I didn't... because it was stupid.

Anyway, my colleague informed me that I was mistaken. "They're not living there, bro." I was stunned. It sure looked like they were living there. The signs and slogans indicated they were. "It's all an act." I came back through the same area at night a few days later and it looked like he was right. While there were some hard core protesters out there who were physically living in the park, most people weren't. They'd make a big show about setting up a tent and posting signs and shouting slogans when the cameras were pointed at them, but then they'd slink back to campus to hot chow and warm beds at night.
Like many such political actions, it was purely performative.
