It’s because most people on Lemmy are from those US, EU, or “commonwealth” countries, so that’s about all we have influence over. Also Russia and China’s democracies are not looking so hot these days… what kind of pressure is a citizen of one of those countries expected to have anyway.

In my country I can go to a government building and take a huge dump on a picture of our elected leader, and I may get thrown in jail, but I’ll probably be released after a slap on the wrist.
