Doxxing is evil, no question there
Unfortunately, it is apparently becoming a way to resist China's hold on what used to be a free country.
And, if it is the only way to point blame to someone abusing their power and/or authority, well it remains evil but becomes understandable.
The real issue is that China wants control, the Chinese way, and Hong Kong wants the freedom it was used to.
It can only end in tears.
