Isnt the meme basically "prove my justifications are invalid, cause I feel I'm always right and the government is always wrong" though?
Yes, government action needs to have publicly, rather than personally, justifiable reasons for their actions. But that's just as true of people, most especially when their actions effect many others.
No, it's not. At least not unless you're taking a very uncharitable interpretation of what it's saying and overlooking an obvious interpretation that's much more reasonable. It's saying the government shouldn't be presumed right just because it's the government. Governments are capable of being right, and they usually are right about a lot of things, but they need to be kept accountable in cases where they're not.
And people for the most part don't need to prove any justifications for their actions are valid, because most of their actions don't require justifications in the first place. Like, what's your justification for positing on Lemmy? Do you actually believe you need one?
Agreed. Sometimes the government simply oversteps the mark and just doesn't understand what's happening, just imagine how the USA got the crappy reputation of arms dealer, and consider that some people in Congress would probably ask not to look at the papers or the history because they know that it would make them feel dumber
