SIL is always so critical

I feel like I can't even breathe correctly when she's around she acts so pretentious like she's so much better than everyone and only her way of thinking is right and will just tear you down if you believe otherwise. Example her grandmother has a strong faith in God she pretty much called her stupid and said her belief was the cause of all the bad things throughout history. Her grandma fell silent and I looked at her and she was nearly in tears. I have a daughter and obviously I'm going to dress her up in cute girlie clothes but of course that woman (she's one of those women who make feminists look bad) I HAD to dress my child like a tomboy just like she was etc etc. then comes time to pick godparents you can pick two sets of godparents when she found out I picked close personal friends of mine she lost her mind on me like WTF and today which was the last straw I posted a funny meme about Taylor swift and Loki (spent 5 minuets fighting with auto correct trying to spell the actors name lol) and again she goes off on me I decided enough was enough and told her off she goes and says her brother doesn't want to be with me and I don't include him in anything like naming her (I asked him everyday to help me pick out a name and it wasn't until after she was born and named did he say "I like the name Emily" then after he leaves my room for a smoke I'm paralyzed from the neck down from my emergency c-section listening to his mom and grandma try and guilt me into changing our daughters name)then she throws my mental health into the fight calling me crazy and bi-polar (I actually have stress induced anxiety can you guess where the stress comes from?)  just being really petty and this woman wants to be a social worker I have half a mind to save that whole thread print it out and fax it to wherever she applies after she graduates. I tell her she is no longer welcome in my home and she pretty much said she would fight me if I tried to stop her. Thinking about getting a restraining order for myself and my daughter against her I don't want her influence around my daughter.
