Beidou2020 has already admitted he is not Chinese, but an American foreigner. So he is harmless now, his game is already up.
And take a look at Iraq to see how a divisive leader (Maliki) or Syria (Assad) to see how easily they can turn on each other in that situation. And from what I can tell, Indian Muslims hate Modi far more than Maliki or Assad.
These states are leftovers of British colonial rule, pushing together groups, religions and ethnicities that hate each other. They are held together by a very fragile string of communal harmony, that frequently shatters, take Sudan for example. Or Iraq and Syria now. Or India during Partition. The British pushed together what was not meant to be, and it shattered.
This is not the same as China, in which the vast majority of our population are ethnically/culturally/religiously similar. Tibetans and Uyghurs combined make up less than 1% of the population, they do not have the numbers to pose a problem, even in their own provinces there are Han majorities. Whereas Iraq is almost evenly divided between ethnicities and religious sects, same as the situation in South Asia.
But they are the ones who elected such a leader, I did not. The consequences are theirs to bear, just like I will bear the consequences of supporting CY Leung become Chief Executive during elections.
