First, let's use common sense, just imagine you had some unpleasant experiences with Australian people, and you started ask around"Are Australian people all like this?how should I deal with them? " Assume everyone with common sense would konw what the result would be.
just coz the question itself is offensive and unacceptable.
I would not be proud of some people's talk who are originally from mainland China, as well, so are many people from Taiwan, they can attack each other as individuals. But there is no way someone trying to link some sterotype to us, which is just ridiculous.
BTW, mainland China's govement is totally shit and Taiwan's just slightly better, and dont be so proud of that, you far from the mature democracratic society compared with most western countries.
