Well sometimes you think you know someone until something like this comes up. She has shown her true colors. I would no longer associate with her and I would not care if she contacted me again because...... I do not knowingly associate with racists.
Your son does not need racist friends either.
I had a similar issue with my daughter. While she was a senior in high school, she was varsity cheer captain, smart, pretty, straight A student, academic scholarship for college and she dated..... the very handsome, bright, football player from an exceptional family and he was black.
When prom rolled around, I thought nothing of posting one of the beautiful pictures that we had professionally taken on my FB page. WOW is all I can say.
I am from rural MS and after this post, I deleted about 1/2 of my friends and I made a statement on my FB page that I would be deleting racists from my page. I went on a nice rant.... These people are devout "Christians" who are at church every time the door is open. I said they were very hypocritical to spew the hate they did toward me and my family just because my daughter was dating a black guy.
My daughter and he did break up they headed to college. He left for a top notch college and is playing football there. She is at a great college and focused with her college career. Who's to say if they ever reconnect... they parted on good terms because they both knew it is vital to pursue college. They graduated in 2013. Daughter just turned 20.
I am sorry you went through this as well. NO ONE at the school or here where we live in TX thought a thing about it or had anything negative to say. It was the relatives in bass ackwards rural MS that blew my mind. And they have the gall to invite us to anything and everything they have in MS for gifts and money but they can't support and be happy for my child.... NOPE... I wrote that side of my family off in 2013 and never looked back.
