Because they're all symbols of foreign political figures/deceased foreign governments?

No, but if a bunch of people flying Peurto Rican flags swarm the Texas legislature it's probably reasonable to assume that there is a degree of support from people in Puerto Rico/outside of texas.

Foreign support is grossly apparent from the leaked data.

   Individual donors
   36,975 Canadian
   55,870 Foreign
   92,845 Total

   Amount donated
   $4,311,287  Canadian
   $12,532,326 Foreign
   $16,843,613 Total

I think that most people mean "foreign" as foreign government (such as CCP) support, not just support from middle-class Americans (and Europeans) who identify with the protests and happen to be foreigners.

And while it could be that foreign governments have donated with false identities over GSG, it is more likely that they would send in people to figure out who is really capable of moving things, and contact them with cash, tips, and resources.

(I am not commenting on the envoy, as so far have only seen it in news outlets [such as CNN & NYT on the left and Fox on the right] who have not earned my trust - so I do not know what is really happening.)

As a Canadian I absolutely count donations from foreigners in the US and Europe as foreign money and absolutely think that that should be illegal (though I have no clue as to what the current legal status of that is).

There aren't 92k individual donors - some people donated multiple times. There's 90,030 unique emails listed and 2 entries with no email.

Commenting only on the flags themselves and not the protest or the hack:

Canada is not part of the USA.

Trump was a President of the USA not Canada; the Confederacy was made from the bits of the USA furthest away from Canada; and while a literal interpretation of the word “America” in the initialism “Make America Great Again” would refer to the entire continent, it is usually understood as specifically just the USA and not Canada (and definitely not Mexico or Cuba let alone the rest).

Flags are widely used as a symbol of identity. Could be an (excuse the term, I can think of none other that fits) false flag, but there’s a reason why that term exists.

Honnestly, there's a lot more people moving from Canada to the US than the reverse. Maybe there's a desire to embrace the American way (of course, the state media won't touch it!).

When hiring, we get a ton of resumes from Canada to transfer to the US but the reverse almost never happens.

I’ve just looked up the numbers, about 810k Canadian-born people in the USA (2017) and 377k US-born people in Canada (2016).

Adjusting for population sizes (USA has ~9 times the population), a random Canadian is about 4 times more likely to go south than a random American is to go north.

But there’s a reason I was focusing on just the symbolism, and that’s that I know how limited my knowledge is in this instance.

Because Canada is not part of the USA?
