what you are suggesting is we should not fight for basic human rights and give everyone equal opportunity to live (they haven't chose to be born, so why not give them at least a chance to live), instead we should fight for people who are like us? close to us? And we don't give shit to other people dying?
Imagine, Germany bans Russian oil, does it make you a happy if they buy oil from Saudi? For me its same, both sides are killing innocent people, why make a switch then?
