Also, it doesn't matter what explanation you use for the partial immunity - GURPS cares about effects, not justifications.

I agree. I actually prefer games were PCs explicitly aren't immune to social influence or take some penalty from blatantly ignoring successful social actions directed against them. Otherwise it can become largely pointless to even give NPCs social abilities. I've had way too many bad experiences with what you're describing over the years. To be fair though some of it was caused by GMs abusing the social conflicts rules in their games but some was just asinine behavior. Though I do think justifications can matter in play for those fiddly situations that can come up but are too situational to bother statting out.
