If you have heard from mainstream western media that Hong Kong people are "Fascist" and discriminatory against mainland Chinese, well, quite the opposite, Hong Kong people are being discriminated, right in Hong Kong, by mainland Chinese!
The HK government (which obviously is just a puppet of the Chinese government), following their master's plan of colonising HK, is doing everything in their power to favour mainland Chinese and discriminates against local HK people here. Among many other things, they faithfully follow Hitler's saying of eradicating a culture by destroying the language, and destroying the language by starting at schools (see who is Fascist here?)
This article attempts to explain some recent incidents about the eradication of Cantonese, the preference of employing teachers from mainland and the public defaecation habit of mainland Chinese. You won't read these views in mainstream western media, both because of the mainland Chinese working inside them and because of leftist views very common among "highly educated" people.
