I think drones reduce both and as such are a good thing, if one is going to be at war. Recall how in VN the VC suffered 2million casualties? Lots of that was due to collateral damage. Or in Afghanistan how the Russians decimated the enemy? That's traditional warfare.
The issue with remoteness and 'coldness' is an attempt to make this approach less palatable (appeal to some kind of war ethics?) on the other hand, if we were sending personnel on foot (a la vietnam) and people (soldiers) were dying by the dozen daily, people would feel aggrieved too (naturally).
Therefore I think what people should protest is 'war' not just a 'kind of war' because, to be honest, this new kind of war, if there needs to be one (and that's debatable of course), has its advantages over traditional (and that's becoming less traditional) warfare. It's less bloody and incurs less collateral damage is more targeted and effective.
So I think psychologically perhaps UAVs seem asymmetrical and unfair to a technological backward foe but realistically, they are at a huge disadvantage in traditional warfare anyway.
As weird as it sounds, I think UAVs are more effective and antiseptic than traditional warfare and thus 'better' as compared to boots on the ground.
