If you need to wind back the clock before any of us were born to achieve a "gotcha", you're doing a disservice to whatever educated audience remains. Your what-aboutism opens a gaping hole where a point should be.

Ideological differences are gigantic valleys between nations in conflict, that's the point.

When one side shouts God's name as they butcher & jihad whoever's in their way who isn't a fanatic like them, the ideological differences can't be mended with "c'mon now". When one side thrives on martyrdom and human rights violations for breakfast, it's not a time to say "maybe we should look at what they're trying to say, are we just not listening?"
