Do you think my neighbor’s friend was being racist?

My neighbor’s friend has a big mouth. She can say stuff that’s hurtful and very mean. She seems polite, but she has said some racist things to people. She said black peoples are the devil and they need to go back to Africa where they belong. I thought that was so mean!! Wow! She said Mexicans need to stay back and they’re all illegal immigrants. She is very brutally honest and speaks her mind and always pointing out people’s faults and weaknesses. She never keeps her mouth shut. My guy friend told her off about being rude towards his girlfriend (who is black). Wow. I told her why did she say all that stuff. She bluntly said, “Sweetie, it’s the truth. I’m just speaking facts and you guys are old enough to hear these kind of facts. To put it bluntly, young people like you are young and stupid. You kids don’t know a damn thing about the world and that’s why people your age get into trouble and are so careless. Young people need to see and hear the reality of like, just like not everyone is going to like you! Not being mean, just brutally honest.” Wow!! 😳😳😳😳😳😳😳😳😳😳
My dad, his girlfriend and my grown siblings aren’t really fond of her.
