For some reason, you correlate anti-American, pro-China views mainly with China challenging our sovereignty when that is not even an issue. You can be anti-American and pro-China in many other ways.
To put it blatantly, from what I've seen, you seem to care more for the "rise of China" and its interests than you do of the U.S. Furthermore, you being either Chinese or Chinese-American causes further speculation in your loyalty and support. Although, that is but a mere secondary factor because there are many Chinese-Americans who are pro-American.

Also, I just briefly went through your post history and I'd say any of your posts involving China were pro-China. Not necessarily anti-American but they still mean something. I'm may be wrong in saying this but, in my opinion, your loyalty to is China and not the country where you currently reside and make your home. That would pro-China, anti-American in itself.
This post, in my opinion, describes your attitude. If you had to make a choice in any issue regarding China vs. U.S, you would choose China every time. It "seems" like I've already mentioned, that your more interested in the rise of China than the domestic and global interests of the U.S.
