If I were to (entirely ICly), express disdain for an infiltrator solely because of his choice of class, would I be in violation of the IRs? Keep in mind that I wouldn't be directly telling him not to play the class, just that my character would be disgusted that a noble would stoop so low. I understand that IRs aren't to be touched with a ten foot pole, which is why I'm getting clarification before I develop my characters in that respect.
