If so why is this particular instance not a good example of it?
And this case in particular, anyone who reduces an 18 year old Chinese kid, who had no choice in what system they grew up in to "the CCP", not even treats them like a real individual, they have a lot of poison in their heart and I think don't care about liberty, or education or democracy as much as the pretend to do.
I specifically mentioned the CCP to distinguish it from Chinese citizens who I consider to be oppressed by the parasitical CCP.
Your position regarding not using the tools of an authoritarian entity against them is untenable. Would you also refuse to use the the mass surveillance apparatus that the CCP has constructed to find weaknesses in their system to exploit with the purpose of bringing out revolution in China?
No, the intent is to discriminate against Chinese people. I've lived and worked in Japan, stereotyping of Chinese and Koreans as the article points out is common. If you wanted to convince young Chinese students of democracy you'd probably take them up on the opportunity to educate and have a dialog with them. That is the liberal democratic way, instead of aiding their government in censoring them.
There's nothing democratic about some random person at a public institution pulling a stunt like this, they have no authority to do so. If they don't like what students are coming to their university, in a democracy they're free to vote for people who want to change that.
