Both my oldest sons wives ex and current were so called Muslems. Both dig Christmas my newest Grand daughter is being raised catholic. My oldest grand daughter from his ex is a muslem in name only.
She ate plenty of macaroni pie recently it has ham in it. His current wife it's what we eat.
In Islam we see Jesus and Moses as prophets, and a lot of other things are similarly like Judaism and Christianity.
Being Muslim doesn't mean we all follow the rules and enforce them. Im muslim and I drink alcohol and I have done other things that aren't allowed. Like Jews and Christians, muslims also make mistakes and tend to live a life were religion doesn't impact every aspect of our lifes.
