If this person believes in the value of the Chinese government, it is their right to defend that opinion, just as it is your right to argue against it. Of course, the fact that they have a dissenting opinion by arguing that China should be allowed to suppress dissenting opinions is certainly ironic (from the linked post).

Because I believe in china, the chinese government and the chinese system. I will defend what I believe in, even though it's obviously shared by very few people here.

I think it would be unusual if I did not defend something I believe in.

And yes, you may think I am wrong, but don't forget that _I_ think you are wrong. What's the difference? If this where a chinese board, you would be the one in the minority.
