You also need to understand I am not ethnic Chinese and nor is my wife. Indigenous people were in Taiwan for thousands of year before any Chinese tried setting foot on the island. Ask any of those countries that sent people here, from the Spanish Portuguese Dutch Americans and Japanese... they were often not welcomed.
Taiwan has never been part of the PRC and even in China's own documents Taiwan was an off limits savage place where they tried to annex the country but could never control it. Also in Singapore there is a large Indian community, are you telling me they are seen as Chinese, the same for the Malay Community? They too are Chinese? How about the many people who are not ethnically Chinese in HK.
My passport says TAIWAN on the front of it. I am definitely not Chinese
