Question: Is there even remotely a legitimate security concern here? Let's say in a hypothetical scenario, the unrest spirals out of control into a state of complete desperation. The HK government and the CCP refuse to compromise on any of the five demands, and the protestors refuse to stand down.
Let's say politically polarized HK pilots and cabin crew are flying a plane full of mainlanders.
Would you be 100% comfortable being a passenger on that plane as a mainlander?
