I am Chinese by my own definition.

Technically I am because I share the same genetic makeup with chinese mainlanders.
Morally I am not because I don't share the same belief with mainland Chinese anymore.

So I am only Chinese by my definition which is different the one commonly used.
If you accept my definition, great. If you don't, that is fine with me too because I am really proud on how far alone I have come in my journey.
