That's not ad hominem. You should learn what ad hominem means.
I really should pay attention to my actual lecture and not skim. My bad. I skimmed and read "your... weak... pack of nerds" and filled in the blanks.
You are right that the rest of the world is enabling China by doing business with them. But what I am saying is that there is a difference between enabling and enacting the laws in the first place. The world enables China. China enacts its own laws. I can forgive the enabling since it is inevitable -- business is business. But the enactment of censorship is unforgivable. Do you get my point?
Initially Mao Zedong in the 50s-70s enacted the initial laws. Of that I blame nobody else other than him, his government, and the peoples of the world that didn't stop him when he was amassing his power during the great revolution. But since then, the world has known CLEARLY what China's stance on government is. "Business is business" is a terrible moral argument for why it's okay for businesses to go there and why it's not immoral for you to buy things from there. You, I, and everyone else that buys products from China are not helping the situation any. Because the government now has all of this power, there's absolutely no way they won't continue their pseudo-socialist regime. So to summarize: yes it's bad they're doing that; you're not helping; businesses aren't helping.
