I think people are arguing at cross purposes. Komikmiha thinks people dont know about certain facts because they disagree with the conclusions he has come to based on those facts (some people are ignorant of them Im sure but definitely not the case for most people here).
People for the most part arent arguing with the fact that other countries have also acted badly or that there are other terrible things going on right now that should have more attention (Yemen, Somalia etc.). Most are just saying none of that means you cant care for the people of Ukraine or that a despot has attacked another sovereign European nation.
You should really go watch some Adam Curtis documentaries about how Russian propaganda has worked the last few decades and realise that it isnt an accident you are stuck in the mindset that everything and everyone is equally awful and theres nothing we can/ should do about it.
