Too well said man. Even though as regular member of this forum, I do find this as one of the criticisms I will place towards this forum too. And the other thing is some of the pro-Chinese bias. They seem to support China too much when in fact there really are problems.
People protesting about HK is all too often and a regular thing, but I don't get how that's supposed to equate a Cantonese empire. HKers' protests in regards to China are usually towards things which disrupts our way of life, from Article 23 which suffocate HK's democratic rights(freedom of speech and freedom of assembly) to Nationalistic Education to surges of mainland Chinese pregnants crossing their borders intentionally JUST TO give birth in HK SO they have access to benefits. The results led to a jump from 20,000 annual birth rates(of this population coming from China) delivered in HK shot up to 74,000 in a few years' time, leading to HK hospitals unable to provide sufficient wards for HK's very own citizens because that population flooded our hospitals. Going further: mannerisms of many of them are terrible. They cut in lines, scream back at you when you tell them to line up, eat inside the train when rules forbid, take a piss or a leak inside a garbage can, spit everywhere..basically causing a disruptive nuisance to our culture and lifestyle. Entering HK, they should respect our cultures as this is the same as you respect the host's rules when you pay someone a visit. It was never Mandarin-speakers that we minded, but rather the actions of the groups which started flooding HK post-handover which cause us so much distress. We protest because we feared as the years go on, HK's culture, identities, would be eroded by the dilution as more mainland Chinese enters HK. Dilution isn't a problem when everyone can get along fine and well together and work together and the differences are appreciated, as in essences should make the society more open and stronger, but what it doing now is splitting the society up in a bad way.
For all of these, they are concerns shared by HKers of all walks and social classes, and DEFINITELY NOT by some "upper class". Actually it's the HK's professionals and middle classes who are severely concerned. The few random idiots who threw the Union Jack were exceptions and doesn't represent anyone. Even many of those with Western passports or received education in the West would not consider ourselves upper class.
Finally, I'm from HK and lived there in the early years before going to Canada. My mom's side went to HK from China a long time ago. In that technical aspect, they were mainland Chinese too. So what's the issue? The earlier generations who went to HK were honest and hardworking. Some smuggled their way into HK and started their life. Things were great back then. There had never been discrimination just simply because of their political identity. It's the post-handover generations which brings with them all these troubles which gives us issues, and it's those who bring with them THEIR mannerisms and troubles which cause us distress who we have issues with.
I recall very vividly of a recent forum thread on Uwants, where quite a bit of waste-of-time HK netizens troll. A netizen identified herself as from China opened a thread asking what spurred the current negativity of local HKers towards mainland China. Her attitudes were very humble and modest, and despite that, she started her thread in one of the worst places possible. The reactions received were astonishing. The forum members there started to reply to her in a very open, honest, and courteous manner, and it's one of the few times I see healthy discussion in that forum. This proves that for all along it's never been against mainland Chinese people simply for who they are; instead it's how someone acts and what they do. This girl was very courteous and everything, and those forum members treated her with respect.
