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

[Anonymous]

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.

People in arguments will resort to whatever insults they think hurts the most, there is no argument rules that say, don't use hurtful racist comments.

It doesn't mean someone is racist, it means they are simply trying to hurt the other person to maximum effect.

I'd be more concerned that she is going that far to hurt someone in a argument, rather than being civil and working things out, as she'll may use those skills against you someday in a fight.

I was just caught so off guard because she is super sweet to me. I can’t imagine her ever saying something like this

No. Give her a chance to explain face-face. Guessing without explanation is plain stupid. You have no clue what was going down. You wouldn’t make a very good boyfriend assuming the bad about her right off.
Yeah, second thought, you should cancel.

They were in the middle of arguing over something so stupid. I don’t even want to say what it was about.

[Guy13]

Alright.

'... she is super sweet to me.'

The wise man watches how a King treats his servants and his subjects...

People who make excuses for it are also missing the point...

Yes, you should if you are sure that's from her. She's not a nice person.

Should you take insult more than person it was directed to or not?

[EaterPeter]

It is a red flag none the less

[SlothySlob]

If it bothers you so much, leave her.

[Asker]

It doesn’t but it could come back to haunt me. I have an important career

[SlothySlob]

So you're pretending like it doesn't bother you, but it does and you have a reason why it bothers you. Stop lying to yourself. If you're so worries that you won't get pussy anymore, you can literally buy an escort, and at worst a flesh light. And, if your career rewards you with good money, you can literally buy a bride from Lithuania or wherever they get "sold"...

Just ask her about it. See what she says.
