Because you have a wave of far leftest SJW activity that is sheltering people from any critical thinking, making "safe spaces" where people become too fragile to engage with anyone of differing or opposing ideologies. Disengaging the context of words and giving them absolute meanings (e.g. the entire master/slave fiasco, as if the words "master" and "slave" or others have inherent evil, as opposed to the context they're used in, or the case with the Chinese word used here in the article).
