Double standards in SNL joke about "race mixing"

So if you didn't see SNL this weekend, Kumail Nanjiani performed a monologue hinged mostly on how he is from Pakistan and he moved to America and fell in love with, and married, a white woman. He explained how his family back home was very unimpressed with this because they wanted him to marry a Muslim woman, preferentially from Pakistan. Okay. He basically went into this because he made a movie about it that was released this year. That's fine.

He goes on to say that he was reading online reviews of his movie and some anonymous person wrote that he watched the movie and it was okay, but he wasn't into "race mixing." There was no identification as to the race of the man who wrote that. Okay.

Here's where it gets dicey (for me). The host starts a bit about people who would use a phrase like "race mixing" and how nothing good can come from someone like this... Jokes ensue. It is an SNL monologue, after all.

But he spent the first half of the story saying how his own family was very against him having a relationship with a white woman and then complained when a stranger said he wasn't a fan of the concept. How is that fair to treat them so differently?

He didn't say anything about threats or anger by the reviewer. Just that the online poster said he 'wasn't into it."

Punch lines aside, I see this as a double standard. Do any of you see it?

And - to be clear - I am not asking if you agree or disagree with interracial relationships. That is a separate topic entirely and one I am not proposing for debate.
