not the argument he's making, it's more like "russian speakers are discriminated against by the baltic states I'm antagonistic towards, here's my sources: 💩"

TBH yes, the situation with the Russian language in Latvia is horrible.

People who have been born there cannot receive a passport until passing the Latvian language exam.

Not that it is worth another war or military operation.

Edit:

Like other ex-soviet republics did not have such restrictions and it kinda turned out to be fine. In Kazakhstan and Armenia they still speak Russian, I claim that the Russian literacy is on the same level as Latvia.
