The Hong Kong protestors have just sealed their fate.

The HK protestors are rallying for support for Catalan protestors.  These HK protestors don't know what they're protesting about and also don't understand the western mentality.

The West will promote and support independence in Asia but will never allow independence in the West.  By supporting the Catalan protestors, the HK protestors will start to lose the western support.

This is great news for the HK government.  Cheers!
