Why do Chinese hate Muslims but embraced Western Cultures....in the USA they voted conservatives..... what's wrong with Chinese & Viets?

That's why Trump loves them so much. Trump probably even thinks he's part Chinese, or at least an honourary Chinaman.

Christianity teaches that a person must submit to government whereas Islam teaches that their religion is ‘superior’ to government.

They vote Conservative like Cubans given they see too much of the Socialism they're use to that also exists deep in the Democratic Party. The Liberal American Press are useful idiots for Socialism and these people understand that.

The "Muslims" in China ( Uighurs) have been staging protests and committing violence against Han Chinese. China will always crack down on any dissident behaviour.
