I was almost agreeing with you until this one. If you think this is an example of "good discussion" you might want to go try it out with the libs over there to see how effective it is. I can assure you you'll be met with more "aggressive" responses.
Certainly those who have patience and enjoy kindly educating others should be encouraged to do so and maybe they'll even convince some. But at the end of the day this is an internet forum for internet randos, not a political party, and we should not police other users from shitposting and poking fun at obvious wreckers and trolls except when they go overboard or break rules. If you want to go talk with others, go for it. There's even !educatinglibs@lemmygrad.ml if you want to help organise how to properly communicate there and share experiences. But don't come here with your bloated pseudoscientifc "examinations" like you're writing a contrapoints script and expect to be taken seriously.

Just to clear it up a bit, these are three different operations in three different states with three different intents and even different targets. While sad, the framing makes it seem like it was all one big coordinated effort by the "Brazilian Police," which is actually divided in command on a state level (and are very independent from the government). For the Yankees, it'd be like reporting people killed in USA police operations in California and New York in a single breath. This is a common trick of Gringo news to make it seem like third world countries are more dangerous than they actually are, coupled with only reporting on them when tragedies happen.
