How do Hongkongers see HK diaspora?

So, I would like to hear your take on Hong Kong diaspora members who were raised abroad. How do you feel about them and their connection to HK?

To give you an example: Europeans find it strange when Americans call themselves "German-American", "Irish-American" or "Italian-American" when they have no familiarity or knowledge of the cultures of those countries and ethnicities.

Similarly, how would you react to those kind of labels? I.e what do you think when someone identifies with the country of their ancestors and the country they live in? "Hong Kong American", "Hong Kong British" etc.?

Would you see them as Hongkongers or are they just foreigners to you?
