Weird

Am I wrong to feel some type of way about if my girlfriend who is 21 receives a text at 10:30 pm from her uncle who is asking about music recommendations and what kind of music she likes. I had explained that I feel a little weird and disgusted honestly because I am Hmong which is an Asian culture. And in the hmong culture it’s sort of okay that you date or even marry your relatives, I had also explained that even if he’s an uncle it’s still weird because he’s a guy at the end of the day and you just never know with guys honestly whether it is just innocent or not. Just want some opinions on this situation.
