The OP post is not a fake scenario. There are examples of liberals advocating for anti-Russian racism in this very thread. It’s rather amusing that you would compare OP to MAGA when the group that best represents the liberals in the meme are Blue MAGA (at least when it comes to USians, as there are countless frothing Russophobic Euro-libs too). This “division” is not being “stirred up” by OP, it is already a readily apparent and prominent source of political animosity in the real world as well as here on lemmy. The position a person takes on this issue also says a great deal about their understanding of geopolitics. Are you a fed, or are you really that ignorant?

Its government came to power as a result of a US-backed coup, for starters.

edit: For the record, I upvoted you because your question is fair and valid if you don’t know the history and context of the situation. And the western media where many people understandably (if sadly) get their information from will never provide that history and context. That is why we get these confidently ignorant people coming into threads like this gobsmacked that anyone can deny what they see as the obvious truth of Russia’s “unjustified invasion by a foreign aggressor.”
