> about all these complex situations

It depends on which side we are on, that determines how the conflict needs to be sold to the on average decent but apolitical person like yourself. As allied against nazis? Not complicated. Fighting russia's invasion of Ukraine? Not complicated. Fighting against Palestinian resistance to their genocide? Complicated. But like South African apartheid turned from complicated to simple over a few decades so you will be dragged along eventually by us "political" people.

It even works with other things too, like people starving on the streets or ~25k people dying from no health care every year, its "complicated", it will always be complicated (until it isn't).
