I'm always fascinated by how someone scolds someone else for calling out bad behaviour. How they actually it? It is such a ridiculous argument no matter what they say. What did DD say when he tried to scold her?
A few weeks into my job there were jokes flying around about race and homosexuality. Now none of these people are overtly racist or homophobic but clearly there is an issue if they think this kind of thing is funny or appropriate.
Jokes of this nature make me enormously uncomfortable - especially so in a work environment because I can't give them a mouthful like I would in my personal life. I find it difficult to address.
I took my boss aside (he was a part of it - I'm his assistant) and told him that as the CEO he had a duty to conduct himself impeccably and that the incident that just happened was completely inappropriate. He told me I was being too "PC" - it was just a joke. I told him PC is a word for racists and homophobes not being allowed to express their views publicly without condemnation. Is that how he wanted to be perceived? As a racist and homophobe?
Racist and homophobic jokes are jokes are for racists and homophobics - it is a pretty simple concept. Nothing "PC" about it. He understood my meaning but months later he REALLY understood my meaning when he met a 'real homophobe' (his words) and was disgusted by the things he was saying and called him out on it.
Same goes for is situation. The "PC" argument has even less merit (if that is even possible) given DDs ancestry. She gets to choose what bad behaviour she calls out - not her dad. Why should she have to tolerate that kind of ignorance? Let alone call it uncle.
He is completely out of line. X is completely out of line. Your DD was the only adult here. Even if he thought there was nothing wrong with it it is not up to him to set HER boundaries. So he can just fuck off.
Remind her that she did the right thing, that you support her 100% and that she doesn't have to tolerate that kind of ignorance. What she did is how change is made in this world. I for one am proud of her.
