No, you're not insane. The picture just standard liberal/imperialist drivel. It's absolutely ridiculous to anyone who is not a liberal. Like,

Fuck the Chinese government

Oh noooooo, random kid posted an insult online, clearly this undoes a century of history and the CPC has no choice but to dissolve in response to this oh-so-impressive action.

#FreedomForHK

They even put a HASHTAG! Oh, the horror! The Chinese goverment is powerless against the HASHTAGS!

[blah blah blah] be on the right side of history

The advance of history will inevitably destroy the rotting US empire that the person posting this is most likely from. Maybe even within some of ours' lifetimes. But sure, let them talk empty words about "the right side" while they can. It changes nothing.

It's perfectly valid to laugh at such a display of liberal brainrot.
