Out of curiosity WolfMunroe, what date did you buy your Bestiary 2? I've had mine for several years now, and the text is slightly different than what you quoted, and the words "reacts to" definitely appear there, as quoted below:
"Negative Energy Affinity (Ex) The creature is alive, but reacts to positive and negative energy as if it were undead--positive energy harms it, negative energy heals it. Format: negative energy affinity; Location: defensive abilities" (Bestiary 2 p.299) Direct word for word quote. I also looked it up in the Advanced Race Guide, and found those words "reacts to" in their description as well.
This leads me to believe that it is possible this grammar issue may have been altered in subsequent releases of the Bestiary 2 after I bought mine. Possibly Paizo put out an official erratum on this issue, but if so, where would we find it?
Either way, I think we can agree to disagree, and personally I'd go with the good ol' role playing game standby: It's the DM's call how he wants to handle it. Either interpretation could be correct, technically, it's a question of how you understand the sentence, which is ambiguous enough to lend credence to either interpretation.
