You touch on the problem I keep seeing people walk into.
Namely, they have a moral compass, and belief structure conditioned in a particular way, and they imagine the world is ultimately full of people 'just like them'
So, what we see is a lot of people saying "if we just do X, or they just do Y, then both sides can stop'
i.e. it is a call for the moral high ground, thinking the other side sees the signal and wants the same thing.
What they all seem to be missing is that some regimes already think they have the moral high ground, and would use it to inflict the most heinous of acts on everyone else, should they ever be able to.
I don't always agree with your view, but on this, I do. This flag waving shite has become a social trend. How people don't see it, I will never know.

Case in point: this patch off of a dead Russian soldier translates to basically "We will take back what is ours".
In addition to Ukraine, they clearly consider Alaksa to be theirs. Finland, Sweden, Estonia, etc. too from the looks of it.
Not a one-off either. These patches have shown up by the thousands.
Ideology is a dangerous human trait, and so is the desire to see the good in everyone - even while every indicator tells you otherwise lol.
