How can I get my sister off my back?

As you may know, I am an atheist, and my sister is a Christian. I respect her beliefs and have never tried to convince her that her beliefs are wrong. However, the case is not vise-versa. All the time she is trying to shove her faith down my throat and even when I comment on religious things here she always seems to need to comment saying, "God is the only way and all others are wrong...yeah you...Isiah. - Your Sister". I am sick of it! How can I get her to respect me and quit shoving Christianity up my rectum?!
