You talk about Pakistanis speaking against China? I tell you, you will find more Pakistanis speaking against Pakistan and its armed forces.
Most of the Pakistanis are fighting the paid trolls on twitter against those traitors. You can get the idea after our opposition parties haven't approved a bill (in Senate where they are in majority) that was required to fulfill some FATF conditions to get out of the grey list. You will see many supporters of these opposition parties fully agreeing with the anti-Pakistan move of rejecting the bill.
Most of these parties are foreign funded, and they in turn pay money to the social media trolls. Of course, we can't stop them from making accounts of PDF. They create threads against the state, armed forces, Pakistan's friends, etc. They are eventually banned, but before that, they are successful in inflicting some damage already. Then the next lot comes. Same happens on twitter.
That's why I am against western form of democracy.
