Intelligent Undead vs Intimidate

[Ydaer Ca Noit]

Ok lets say that someone plays an intelligent undead, and someone tries to
1) Demoralize him
2) Make him friendly with intimidate
Are both of those possible? Or even one of them?

I know that
-A character immune to fear can’t be intimidated, nor can nonintelligent creatures.
-Undead have:Immunity to all mind-affecting effects (charms, compulsions, phantasms, patterns, and morale effects).

But here comes the problem:
-All fear attacks are mind-affecting fear effects.

It is right there in the SRD, but I can't find this anywhere in the MM or in the DMG or in PH...and my DM doesn't accept the SRD as accurate, so I can't prove that intimidate fear is a mind effecting effect.

Thanks.

My opinion is that a skill check is not a mind-affecting effect. You are not immune to diplomacy or intimidate, maybe I would give a bonus on intimidate but not immunity.

Ok so now I have to just prove that a use of the intimidate skill counts as an attack.

"Fear (Su or SP): Fear attacks have have various effects. ......... All fear attacks are mind-affecting effects"

You cant take the last sentence out of contexts. It talks about fear supernatural and spell-like abilities.
