A cousin of mine has been a Catholic, and is now telling me she's converting to Judaism — but still has her Mother Mary shrines in her home, celebrates Christmas, etc. She's posted pro-Jewish comments, which I fully endorse. However, she's also begun to post in-your-face items which almost smack of defamation of the basic tenets of Christianity.
Today, she posted this on her FB page. Apart from the obvious comparison of Jesus with Muhammad, there is something inherently wrong with it, but I can't put my finger on it . I looked up the author of that tweet, and I'm not impressed with his/her ideas, language, nor communication style.
