Yeah. The key to actually holding both sides to the same standards is taking into account the context, not ignoring it whenever convenient. The Chantry are explicitly colonizers who use the convenient excuses of their religious superiority to enact violence upon "heathens" and then justify it with a thinly veiled Manifest Destiny. And really, viewing the Dalish response to that as anything but reacting to a very real threat to their culture and lands is ridiculous. What should they have done? Welcomed the humans into their midst and just given up their homelands without a fight?
Context? The Context of Human settlements coming under assault, innocent civilians being murdered along with Chantry Representatives isn't a clear enough justification for war? The Cult of Andraste granted the Dales to the Elves, the Precursor to the Modern day Chantry, the Chantry has every right to "retake" the "elves" Land.
So there really isn't any of the context you try to proclaim to, the Chantry doesn't need to colonize or invade territories it can cite ownership of.
Sort of like Kurdistan being a part of Iraq, and Iraq having the sovereign right to claim such a state and territory does not exist.
