Yes, and I'm arguing that a rational mature society should be capable of allowing people to express their opinions and then engaging with them if their opinion is perceived as wrong or incorrect. If, after a reasonable discussion in which everyone is able to clarify their thoughts and opinions, they are still deemed to be too extreme (and I mean genuinely extreme, not simply contrarian) then they can cut ties.
But that isn't what is happening. There is no reasonable discussion. There isn't even any attempt to understand the complexity and nuance of a situation. It's simply: you're gone. It's mob politics 101 and anyone familiar with political history has seen it time and time again.
The main consequence of this mentality will be that organizations like MIT will be filled with yes-men/women and those that toe the intellectual line. And subsequently the real losers will be society and MIT.
