A racist in non-secular clothing

I need to go away. 
Someplace all by myself. 
Just me. 
A pile of books. 
Some nice and healthy food, with the occasional field trip to find junk food. 
Wine...probably not, as it is supposed to interfere with my high blood pressure medication. 
O.K., diet soda, then.
Quiet.
Naps.

Yeah.  I could use that.  I can do that in a few months when the place I work is closed for remodeling, but I just need it today.  I am so tired of dealing with the crap buffet here.  I am worn down. 

Then, today I was helping my friend the nun and her friends and totally out of the blue, she brought an issue into the conversation and when I disagreed, she resorted to racism to make her point.

What the fuck?

When I challenged her on what she had said, she condescended to me by rephrasing and explaining her comment in the guise of social responsibility.

What the hell?

I continued to hold my ground on this and she kept talking, just making it worse and breaking my heart.  I mean, this is my friend and who knew she harbored such beliefs.  I mean, she is a nun, for crying out loud.

So, I just let her talk and looked in her eyes until she ran out of steam.
Just hoping that I would see some awareness there. 
I said what I had to say. 
Again. 
She thinks that I am too stupid to understand her premise.
Perhaps I am just too stupid to be the kind of friend she mistakenly believes me to be.
What is there about our relationship that she thought it was safe to say that?
I mean, did she just meet me?
