No parts of the war are good - I didn't make any claims about the Russian war, I don't know what caused it or why it's going on, and I don't like wars. I don't believe most claims by either side, I doubt there's advantage in revealing the real reasons by either side - the articles we read are to craft an opinion either to support one side or the other and I don't think it's that simple - that's my whole point. I don't need to think a war is legitimate to have a reaction to someone saying there's one country with warmonger people and one country without. In general I think it's normal to side with the invaded party and I'm personally inclined to support that side - but it doesn't mean I tell myself I'm making some informed decision.
Not really, but to declare a whole population as "very bad thing", yes I need to approximate first hand observation. I have no need to declare a whole population bad though.
