The Architect is an even worse rape abomination than the rest of the darkspawn. If you're actually arguing that the darkspawn aren't evil but humans are, in this setting, you're ridding a kind of crazy train I don't want to be within 100 feet of at any point.
And if you're going to start saying that Genitivi - and by extension, the developers - are making false accounts to slander the Dalish then, again, you're full up on a crazy train none of us want to get on in any way.
Generally, we're back to your apparent endorsement of racism. The people who support the Alienages - which aren't all the same, mind you - range from Rivani to Free Marchers to Fereldans and Orlesians. Fereldans had nothing to do with what Tevinter did to the elves. In fact, their predecessors were busy being massacred and enslaved by Tevinter.
Orlais specifically had a war with the Dales that it won, but that has nothing to do with what Tevinter did to the elves.
The Architect heals dwarves and Wardens that happen to get lost in the Deep Roads and then helps them get back to the surface, unharmed. (See A Different Darkspawn, Codex of DA: Inquisition obtained during Vallamar quest, the one with Bianca Davri).
Please do not judge the character so harshly. Is he hazardous because of his intelligence? Yes. Does that make him evil? Is a being that strives for the preservation of life at his own risk evil?
Try to see the other side of him. We all know his plans pose a...situation that cannot be easily solved, since it can either evolve into a serious threat or pose a social problem for the future (coexistence with darkspawn). That does not mean he deserves to be considered a vile abomination.
The Mother was an abomination, as well as all the darkspawn that followed her. They willingly tricked, tortured and killed innocents. The Architect? A darkspawn that protects people from the malice and belligerence of other darkspawn? Who fully understands the threat his kind poses to every living thing in Thedas and teaches the darkspawn to stay away from humans and to be peaceful? A rape abomination? Really?
