I am Taiwanese and I say that Taiwan is part of China.
Demon, I find your analogies very interesting. Are you Taiwanese? If not then can you please read up on Taiwanese history? I suggest one by Professor Qi Jia Lin though its in Chinese. There's one by Lian Ya Tang (if I can remember).
Thing is this: if Taiwan wants independence, she would have to fight China and become a US military garrison. That's not true independence, isnt it? I personally advocate Taiwanese independence and the only way that could happen is through reunification with China. Only then would we be truly independent from the US and Japanese influences.
