"Kids fighting for Democracy".....You realize that there were elections recently in Hong Kong where the 'pro-democracy' (anti-governemnt?) forces won handlily?
We live in such a looking glass world these days -- apparently democracy isn't about one person, one vote and all that but rather engineering the contest to get the correct result.
(I'm also a bit amused by pictures of those students waving the US flag. Assuming they'd qualify for a visa.....that's a pretty big 'if' at the moment even if there weren't exclusions because of the corona virus -- then they'd find that life here isn't that good at the poor end of the spectrum, especially if you're a foreigner. Assuming they could get a decent job -- something in tech, for example -- then they might find the FBI breathing down their neck, checking for Intellectual Property theft.)
