I have no opinion on whether it actually is disrespectful, and I'm not weighing in on that. However, as a point of conversational order, if someone states that something is disrespectful, it's better if they say who they think is being disrespected. Otherwise, the statement is so vague and ill-defined it's hard to know whether to agree or disagree. In other words, if you don't know what is actually meant, how can you challenge it specifically? The only way I know is to guess at all the possible meanings, then address all of them case by case, which seems a little silly.
