Should I call things off with a girl that said a racist comment on Facebook to another girl?

The girl I am dating once told a Latina a slightly racist comment. This girl ended up taking a screenshot of her comment and sent it to me. There is no context at all on why she said this. All I have is just this one comment to go by.
She was making fun of her for having a Mexican sounding last name and assumed she had father issues or something. The girl had told me she was going to keep showing this to every single guy that comes into her life and wouldn’t ever stop.

The girl I am dating posted a picture of us on her profile and tagged me in it. That’s how the Mexican girl was able to find me. I am worried about this somehow coming back to haunt me if she says things like this? What will she say to me? Is this a red flag? I am also white if it matters.
