Well, my char is not social fu expert but I have his social stuff boosted up quite high in one vs one interaction. Also if I would try manipulate your char it would not be change her completely different person. Simply said my char would try ask her join his cause willingly. But as if you have high conviction it means I would need succeed several times to make you do something supportive to his goals before you create enough commitment to create intimacy for it.
Also as I know using social fu against fellow player can 'rub wrong way' so that's why I wanted carefully talk about it OCC so I do not cross the comfort line what you have for social fu applied to your char. But as note using presence skill alone is not detectable as any fashion as mind control, but as social manipulation or simply charming. I understand you could full ballistic if you figure out I tried manipulate you (basically trick you with social fu) but would your char take similar aggressive offense if she feels my char is merely seducing her (and quite effectively) to his cause? You can resist seduction (and so do not build any commitment or intimacy) but you likely feel 'strong temptation' as sign from my attempts. If I would use manipulation you would feel 'you were attempted to be tricked' (which I understand would be a thing what you would take as a attack and so proceed for counter attack).
I do plan go through charisma+presence route than manipulation+presence (which in itself provokes more hostile response if it fails). using appearance+presence whenever my char wants seduce someone to his bed (if he would like build relationship he would use charisma+presence but he is not interested build close and personal love relationship with compassion what he is having).
Anycase whatever I will try 'inflict' with my social fu is not meant screw over your char concept nor wrest control off you but rather try make your char 'team up' with my char. Just wanted approach this goal through game mechanic method than just agree in OOC 'that will happen'.
So, sorry again if I offended you any manner with my suggestion. If you feel still eery about my char using social fu towards you (and not be party friendly method) I will then back off from idea and use social fu only against npc's. As it is one things needed discuss on table before exalted game begins is social fu allowed towards circle members and what way it is allowed. I just thinked use my social fu to form stronger bond between circle members (to create connections and common interests) than instead enslave whole circle under my reign
