So, what happens if a bunch of people decide to walk through their "safe space" and act together to passively destroy their little camp. Not harming anyone, not violating their right to be in that space, not physically moving people or using force, but just being there. What would happen? A huge fight? A riot? What if 500 people just showed up, linked arms, and started walking all through the crowd and in and out of their "perimeter"?
They would be officially "offended". That would make it wrong on that campus. DOJ would be called in, and they would arrest those moving through the "safe space" and charged with a violation of the 1st, and hate crimes.
Meanwhile, those other students (99%) just want to go to school and learn engineering, Geophysics, biology, and other things that are going to earn them a great living and possible get some random sex with coeds.
