Well, despising people and thinking of them as a monogamous group based on nationality is neither rational nor positive. Plenty of Russians are against this war, and whatever is currently done only serves to empower those who benefit from it.
I have relatives in Ukraine, Dnipro to be exact, and they were under rocket strikes. I feel afraid for them, and I would love to stop everyone who enters the battlefield - and have no mercy for those going there by their own will.
But I also understand that blatant hatred is going to do nothing but empower “us against the world” mentality. What is your preference - to be able to spew hateful messages or to try and make a change? Without understanding the drivers behind what happens, you only play into the deck of those who escalate the conflict, while also supporting suffering for those who never deserved it - crucially, on both sides of the frontline.
hate leads to suffering
(as much pseudo-philosophical as Yoda is, here we really have to do something before it breaks so many people)
