Living in the south

We recently moved from a Indianapolis to rural Alabama to be closer to family and for a job. I'm also 21 weeks pregnant. I've noticed here that a lot of girls and women go by their first and middle name or they have two first names. People keep asking me what we're naming her and I tell them we're naming her Grace then so many people look at me and say that's it? Or ask why? Because I fucking like the name that's why.  I want to punch them in the face. Not your kid, not your uterus, not your choice. Sorry I'm not naming my kid Ellie Rae or Laura Beth like every other person here. People have been going by only one name for basically ever. 
Anyone else relate?
