-"F***** up... Never disrespect anyone's religion. Just comes to show how immature and logically unstable you are...."

-"Wow that's so offensive, you are a disgrace to your children....I think they should be with their father , obviously a better roll model than you will ever be!"

-"I'm not that religious, just lost all respect for you. That is disgusting."
