There is no discussion. He's a racist hypocrite with a double standard between human freedom and elven freedom. There are those who see that and those who refuse to see it.
He might be all of that, and worse - but IME, when people post such declarations on internet forums, it is for the purpose of discussion.
Okay, he fought in battles against Orlais back when it was actually oppressing Ferelden, but I don't see him actually risking his own hide in the game.
If he's recruited as a GW, he'll not only fight hordes of darkspawn, but also volunteer to slay the archdemon, knowing it's suicide.
You might also note that it's customary in the setting for army leadership to go into battle with their troops. If you ever played the human noble origin, you'd have heard the Couslands expressing some angst about Bryce & Fergus going into battle, and King Cailan also led his troops into battle. Military leaders didn't sit in bunkers watching it on a monitor and communicating over radio - they were on the field.
I don't think it's any coincidence that the man spits the word "elf" like it's poison when he's trying to rationalize selling "elves" into slavery; like somehow being "elves" decreases the severity of his crime. And despite "Ferelden's independence" being his claimed objective, selling his own people into slavery is the crime he loses the least sleep over. I guess slavery is only an unforgivable travesty when it happens to him and his. "Elves?" It's totally fine.
I think you're making a lot of assumptions there. He does acknowledge that he committed crimes.
At least they're indiscriminate about who they pick, and make sure they actually need the person before conscripting, and put it to a noble cause of, you know, keeping all life from being wiped out on the planet.
Are you talking purely about GW here?
I'd be surprised if Loghain managed to defeat Orlais without conscripting large numbers of humans. Some of the armies he commands during the game may include conscripts. It goes with the territory.
Unlike this selfish idiot, who chose to ignore everyone around him telling him "This is a Blight. We need the Grey Wardens. We need help. This is a Blight. We need the Grey Wardens. We need help." Then waited until the entire country was overrun with darkspawn before he would consider changing tactics; either step down from his regency to end the civil war to focus on fighting the Blight (since the only reason the nobles rebelled was because they saw him as a power-grabbing tyrnat), or sell his own people into slavery to fill his own coffers to keep fighting the civil war to keep trying to force the nobles into line while ignoring the Blight. He decided slavery was the better alternative to admitting he was wrong; and he was fine selling "elves" as long as it meant defending his own power.
Loghain had 3 major flaws driving his behavior in DAO:
-- His irrational (?) fear of Orlais
-- His mistrust of the GWs (who had previously been exiled from Ferelden for legitimate reasons)
-- His denial that it was truly a blight, and ignorance about the need for the archdemon to be slain by a GW.
With Cailan and the Couslands gone, he was the highest-ranking noble left in Ferelden - unless you want to count Howe as being Teryn of Highever. I think it's only natural that he would assume the role of regent under those circumstances. For all we know, he may have been trying to prevent a Civil War and/or avoid the chaos of anarchy that could result until the leadership questions were resolved.
The darkspawn would have had to overrun ALL of Denerim to even reach the alienage. They would have had to get through the outer city walls and storm the human city districts to even reach the alienage, which is somewhere near the center of the city.
Which is pretty much what happened.
