In context, it's refering to the fact that normally, when DR "soaks up" all of the damage, no special effect tied to the damage is effective. Since "normal" touch attacks don't (usually) do damage,
But they do. A
Ghost's Corrupting Touch (su) does 1d6 damage as a touch attack, and it isn't energy damage it's just listed as damage, there are various other creatures with Incorporeal touch attacks that do damage or damage and some other effect.
Hence to me the sentence "Damage reduction does not negate touch attacks.." shows that DR does not negate the damage of a touch attack.
If they wanted DR to apply against normal damage delievered by a touch attack but not the other stuff, why mention the touch attack at all.
Look at the Wraith's attack for example.
Incorporeal touch +5 melee (1d4 plus 1d6 Constitution drain)
"Damage reduction does not negate touch attacks, energy damage dealt along with an attack, or energy drains."
To me that means neither the touch attack (1d4 damage) or the energy drain (1d6 Constitution drain) are negated
They could have said.
"Damage reduction does not negate energy damage dealt along with an attack, or
energy drains."
Now to me that would mean the Constitution drain isn't negated even if the touch attack damage is. Just as a flameblade doing 1d8 normal and 1d6 fire has the 1d8 normal damage countered by DR but the 1d6 energy damage not because of the sentence above.
Again: Don't take the troublesome sentence out of context. I'll get you in trouble.
You are doing worse you are not even taking the whole sentence, your ignoring the stuff about energy damage and drains, why would touch be mentioned along with them unless like them DR does not negate them?
Touch is mentioned because like inhaled poisons, energy damage and energy drains it doesn't need to defeat external barriers Damage Reduction like armor or touch skin to effect the target.
The fact this makes Wraithstrike even more broken is neither here nor there.
