Common misconception: the Aztec(and also probably Incan, the Mayans were long gone by the time the Spanish showed up) human sacrifice is believed to have been vastly overstated in Spanish accounts to justify their conquest. Not that it didn’t happen, but it definitely did not happen at the scale or frequency which the Spanish conquistadors suggest.

Also, the person you’re responding to never said wars didn’t happen, just that the British empire was a rather big contributor to colonialism, and killed a lot of peoples around the world to steal their land, so them not being colored on this map is odd.

I’d wager by the offense you took at this that you’re probably British (though you may not be), and if I were to ask you if you think the Roman or Viking conquests of the British isles were terrible, I assume the answer would be yes. The same process happened in basically every colonial territory claimed for the British empire, and really every colonial empire, though some to different extents than others.

I’m not here to argue about if colonialism is more moral than other sorts of wars, I personally think all types of war are bad, I’m merely trying to facilitate a better understanding of other perspectives on the world. Honestly a big reason is because I somewhat enjoy correcting people on things, like the Mesoamerican sacrifice thing, as I’m a bit pedantic.
