since you quoted me, well, restricting the right of someone active to stand for election is controversial; I link what Glob. Times had to say:
Disqualifying Joshua Wong is a law-based righteous, reasonable decision
Why is it controversial? Please elaborate!
This is typical MSM trying to smear Hong Kong democratic processes.
In all the democracies around the world, people are barred from standing for all sorts of reasons! Having a criminal records being one of them for example!
In Joshua's case, he has openly called for Hong Kong independence, an illegal act under the law of Hong Kong and China!
Also, once elected, all elected members have to swear allegiance to the Chinese government and promised to uphold Chinese law!
This is no difference to other countries. In the UK for example, all elected MPs have to swore allegiance to the crown. If they don't, they would not be able to participate in the affairs of the land!
In Hong Kong, this has already happened, and the members involved have not been able to take their place in the elected council, thus wasting people's time!
It is clear that Joshua, from his past actions, that he would not be able to swear his allegiances to China, and promised to uphold chinese laws! And as such, under the law of Hong Kong, he is illegible to stand for election.
Absolutely nothing wrong or illegal about this!
