It is unfortunate for any house of worship to burn down. It is horrific if it is arson be the house Christian, Jewish, Muslim or any other faith.
If arson, this is an act of hate. If someone dies it is a murder.
If arson, this activity has no place in America or any part of the world. I know Christians and Jews are persecuted in the middle east. I know their places or worship are destroyed. That is there (and not right) this act is here and not right.
