What do you mean by 'revolution', rioters in Hong Kong?


On Tuesday, three judges in the Hong Kong Special Administrative Region found Tong Ying-kit guilty of secession and a terrorist attack for hitting three police officers with a motorcycle on June 1, 2020. Further, on the motorcycle he carried a black banner with the words "liberate" and "revolution" on it.
Tong committed the deed on the second day of the National Security Law coming into effect in Hong Kong, according to which he was charged.
Some defend him by saying that "liberate" and "revolution" do not necessarily mean secession. Tong, of course, has the right to get lawyers and the latter have the right to defend him, but we all know what the two words mean in Hong Kong. In theory, since the very moment of Hong Kong's return to the motherland on July 1, 1997, its people have been liberated from foreign colonial rule; from whom do they mean to "liberate" from and against whom do they mean to incite a "revolution"? The secession and subversive deeds contained in the two words in their slogan are obvious.
The slogan that contains the two words was widely used by rioters that victimized the city in the 2019 riots, with men wearing black beating people with that slogan in hand. It has long become a typical phrase identifying the rioters that openly call for Hong Kong "independence", such as the "Returning Valiant", a radical organization caught making explosives and planning to bomb the court, the railway and other public places in Hong Kong.
So there is no point separating the "liberate" and "revolution" slogan from secessionists. Of course, Tong might be a victim of the evil masters, too, who tried to play him into a cannon fodder with their lies, but the law is the law and he must be held answerable for his crimes.
On Monday, the Independent Commission Against Corruption sued Benny Tai Yiu-ting, a main "mental tutor" of rioters in Hong Kong, for corruption in the usage of their collected funds for election. In other words, the brainwashing masters might have not only fooled their cannon fodder, but also corrupted their money.
Justice will be done.
