Those who doesn't want brexit to go through deserve no sympathy from here since it is hypocritical of them to single any other independence movements ...
There are so many things wrong with this comparison, that I'm more disappointed with it than disagree with it.
They're happening for different reasons. EU and CCP are so far from eachother on the scale of problematic, that they are not even on the same map.
CCP is an authoritarian state that pushes for censorship, puts people in prisons for speaking out against the state, etc.
Hong Kong is fighting to maintain it's way of life, Brexit does the opposite.
I'm not against Brexit in the same way that I support Hong Kong.
I don't think Brexit is in the best interest of the UK. It's not the end of the world though if it happens.
Similarly I don't think Hong Kong giving up is in their best interest. But it's a lot more than that. I think they're in danger if they give up.
Trying to pin these two events as if they are both simple independence movements, with no considerations of what either situation even entails, does a disservice to both.
And frankly it does a disservice to yourself.
