I had to tell my parents, who are mildly Christian based, that I had converted to the Wicca religion. It wasn't nice and pretty at the start, and I had to deal with a load of bad stuff coming from them in the first days.
Eventually they grew to accept it, because that's who I am and what I believe, and they (as I) found that there is no reason why the two beliefs couldn't co-exist.
My grandparents (from my father side) were another whole story. They are fervent religious people, they have a gigantic cross on their backyard and have had priest do mass on their house. I was called child of the devil, witch, Satan himself and threatened by them.
Since then I haven't talked to them, if they chose not to accept me for what I believe then it's their loss, not mine. I will always respect them and accept them for their choices, even though their attitudes really go against what the Christian religion supposedly represents.
