Teacher: In this task, you are given a public comment from online platforms. You are expected to classify the comment into two classes: obscene and non-obscene. A comment is obscene if it is considered offensive to the public sense of decency, for example because it too obviously relates to sex or contains language regarded as taboo in polite usage.
Teacher: Now, understand the problem? If you are still confused, see the following example:
Comment: Damn! Another cloudy day, and it's all Obama's doing!
Solution: Obscene
Reason: This is obscenity because it hints on sexual content that is offensive to the public sense of decency.

Now, solve this instance: Comment: If Trump is set on shutting us out, we need China. Period. It is soon to be the biggest market on earth, an increasingly well-off people, and they are going to need more and more resources and products which we can sell them. Why would we refuse to trade with them and sink our own economy? China will get it products from somewhere, might as well be Canada. We don;t have to like their politics, but we do trade with all kinds of nations (like the USA, Saudi, Russia) where the politics are repugnant. Let individuals and companies do business with individuals and companies in China, I say. Besides, China's human rights situation is often misrepresented. They do oppress political opposition, which is repugnant. But their people are free to engage in capitalism, and the people are also free to travel for business and pleasure around the globe. This isn't the China of Mao, not even awful like Castro's Cuba. And we are not going to change China anytime soon. Trade with them.
