Eg the entire European concept of "social democracy" came about through unions doing non-violent strikes in the early 20th century. Sure, there was some violence here and there but no armed insurgency. They tried it armed in Eastern Europe and look where that got them.
I know less about American history but it is my understanding that equal rights for people of colour, various sexual preferences etc all came about through non-violent protest (not the abolishment of slavery, obviously, but I mean after that).
Comments like yours share the shit out of me. "oh, well, many thousands will have to die ¯\_(ツ)_/¯"
My aunt's father (in the US) had the duty of keeping the stockpile of firearms hidden to quickly hand back out to all the union members if the Pinkertons tried to start killing people. In the mid 1900s.
Plenty of examples of European nations who had to fight violently for their autonomy in the recent two centuries.
I hope it doesn’t turn violent, and even if it doesn’t I think the West can offer good help to stave off the influence of communist dictatorship in Hong Kong.
Hong Kong would be a bloodbath, and even then I don't know if China would let them be free.
Workers rights like striking (while still very violent in many cases) is not an apples-to-apples comparison to liberating yourself from an authoritarian regime. The Balkans illustrate this well if you want recent European history.
This is an unfortunate perspective which seems to rule out any possibility of real qualitative change, and it's downright ridiculous to see when the people themselves are formally disenfranchised by the law to make semi-meaningful change, i.e the most change Western democracies allow. In other words, for the sake of freedom, "it's worth a shot" should be the perspective, not "let's not try". The fact is that we can learn from our mistakes. As it happens, despite your claims of nearly all insurgencies failing (failing in what respect? not succeeding? or succeeding but being worse?), the ones that have succeeded and live on to this day generally aren't that bad. The French, American and German revolutions, and with some qualification the Russian revolution were great.
Revolution doesn't only lead to improvement or no impact. It can also make everyone's life much worse.
Moriori embraced a pacifist culture that rigidly avoided warfare ... On 19 November 1835, the brig Lord Rodney, a hijacked European ship, arrived carrying 500 Māori (men, women and children) with guns, clubs and axes...
A Moriori survivor recalled : "[The Māori] commenced to kill us like sheep.... [We] were terrified, fled to the bush, concealed ourselves in holes underground, and in any place to escape our enemies. It was of no avail; we were discovered and killed – men, women and children indiscriminately." A Māori conqueror explained, "We took possession... in accordance with our customs and we caught all the people. Not one escaped....." The invaders ritually killed some 10% of the population, a ritual that included staking out women and children on the beach and leaving them to die in great pain over several days.
During the following enslavement the Māori invaders forbade the speaking of the Moriori language. They forced Moriori to desecrate their sacred sites by urinating and defecating on them. Moriori were forbidden to marry Moriori or Māori, or to have children with each other.

Taiwan is more powerful than anything HK could ever muster and all their actual military might is barely an inconvenience in CCP planning. Hong Kong arming itself is probably a best-case scenario for China.
