I don't think that a Muslim woman is allowed to have a non-Muslim husband. I maybe wrong but this is likely true and he'll have to divorce you.
I am a former Muslim (born Muslim, now Agnostic). Although I have been under some sort persecution by Muslims at my school and I generally do not have a good feeling for Islam, I don't think your mother in law has the right to do that. She must realize that all humans are the same on the inside and that you are a good person who never wants what is bad for her family.
You must show her that not every Muslim is an extremest and that just like most Christians are moderate Muslims can be moderate too. If your husband would leave you for that he doesn't really love you. If someone who I love goes the wrong way I'll do what I could to get him back or I'll try to accept him/her!
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
