So, hold an intellectual discussion with your friends about the South China Sea in the comfort of, let's say, your home. Cool. But, get into a loud and/or heated debate in the middle of a restaurant or bar while surrounded by Chinese nationalists. Think again.
Furthermore, ask your Taiwanese friends privately—I repeat, PRIVATELY—about how they feel in regards to Taiwan’s relationship with China. Great. But, post a long rant on Wechat discussing your views on the relationship between China and Taiwan? You're just asking for it.
