Okay, so I know that a Cleric can use wands of spells that are on their selected domains even if it is not on there normal spell list as discussed here:

and
http://paizo.com/threads/rzs2mzdz?Scrolls-and-Domains#14
However, I have someone that is trying to take the bold part here and extrapolate:
The PRD wrote:
Spell Trigger: Spell trigger activation is similar to spell completion, but it's even simpler. No gestures or spell finishing is needed, just a special knowledge of spellcasting that an appropriate character would know, and a single word that must be spoken. Spell trigger items can be used by anyone whose class can cast the corresponding spell. This is the case even for a character who can't actually cast spells, such as a 3rd-level paladin. The user must still determine what spell is stored in the item before she can activate it. Activating a spell trigger item is a standard action and does not provoke attacks of opportunity.
They are saying that because domains are a part of the class, that the class is therefore capable of casting it as long as it appears in the domains. Thus any cleric could use a wand of any spell as long as it appears on either the cleric spell list or the domains somewhere, even if they did not select the domains that they appear in.
I personally disagree, and have argued that effectively the Cleric is an aggregate of multiple classes that are grouped under the 'Cleric' name, since the Deity and Domain choices fundamentally determine the spells that a character is capable of casting, therefore your class would be something like "Cleric of Nethys - Destruction/Defense" and not simply Cleric. Meaning you could use wands of spells that are on the Destruction and Defense domain list or the actual Cleric spell list.
So my question is, which is correct? And more importantly citations and logic backing up the way the answer was obtained.
