I think that player are making there Pacifist true Pacifist and not Half-Pacifist.
From a roleplaying perspective, this argument doesn't even make sense.
A true pacifist wouldn't head out with a bunch of adventurers and say "Hey. It's ok if YOU kill enemies right and left, just as long as I don't get my hands bloody.". Such a PC concept is irrational. A true pacifist would try to convince adventures to not go out and fight/kill foes at all. If he couldn't, he wouldn't associate with them. You are running your PC like someone opposed to the Japanese Whaling, but goes on board the ship with them and helps them haul in the carcasses.
Helping others to kill is nowhere near the definition of a pacifist. River isn't a "true pacifist". He's a killer. He just happens to help others do it for him.
You choose to roleplay your PC the way you do. But the feat isn't designed to enforce that on any given PC. That's your choice.
PS. All PCs are killers. Their entire careers are spent "breaking and entering", "murdering", and "stealing". Yes, the players and PCs justify it a lot of different ways, but for all intents and purposes, PCs have a huge body count and end up robbing and killing all types of foes, and often end up getting into battles with very little provocation.
A pacifist player character is an oxymoron. No different than deafening silence or military intelligence.
The whole time... I never been stunned because I build my character around that feat, but there is some power I find much more interesting than the few that doesn't deal damage, but I don't take them because they deal damage and that is against the spirit of River. I would rather take Divine Glow as my 1st level encounter power over any of the no damage dealing ones. So you might not see it, but each time I look at River stats, I see the sacrifice I must do. I even didn't took at first Consecrated Ground daily the first time because it was dealing damage. But as WotC are slowly killing my whole concept, I have started to take more aggresive power.
Again, choice.
That is a roleplaying choice.
I don't see why every Pacifist Healer PC at LEB should get a boost in healing because you decided to run your PC the way you do.
I don't see the need to change the rules to satisfy the way you want to roleplay your PC.
I had a Pacifist Healer Dwarf with Divine Glow and Light of Arvandor. I roleplayed him that he had no problem doing damage to foes. He only had a problem with risking killing them himself. He wasn't a pacifist, he was just adverse to killing foes himself. Just because the word pacifist is (misleadingly) in the name of the feat doesn't mean that anyone should play their PC that way (and by that way, I mean a PC that refuses to damage foes).
And even then, the Dwarf would have been stunned if he used either of these powers against a bloodied foe. So, he didn't. I still roleplayed him (in combat) to choose to not attack and potentially kill bloodied foes.
So just like River, this Dwarf was never stunned. It has nothing to do with not taking powers that do damage. It has to do with target and power selection at certain points in the encounter.
You have yet to specify a reason why the extra healing should be allowed.
You have yet to specify a reason why WotC has unbalanced the feat and destoyed the entire concept of pacifist clerics.
If you really want Healing Word to be Divine, why don't you change the proposal to drop Charisma out of the Pacifist Healer feat as well? That way, River can use it with Healing Word and he also won't unbalance the feat.
