If your Chinese friend called his Taiwanese Buddhist girlfriend a traitor for supporting India over China for religious reasons, is he wrong?

China is a communist empire that is trying to entangle all the Earth into its web of political control. Russia is already a puppet of them that they have been given little choice but to mindlessly obey. America is already a puppet of them that they must fight if they are ever to regain control of their country. India is already threatened with its daily existence by Chinese bullying and threats. The Wuhan disease is now entering a second wave that the new largely untested vaccines do not work against. COVID-19 has mutated as only a created biological weapon can do. It was meant to be evasive and relentless and unstoppable, as the world had always warned about bioweapons. Now it is real and we are living its outcome and not.

No because  Taiwan does not  consider themselves  chinese

Even minus the religious component a typical Taiwanese would support pretty much any other nation over China. So your friend is kind of an idiot. 

Does not sound like a relationship that would last. 

Wrong that he’s gonna piss her off

I dont think anyone here cares.
