well then use the bible verse against them , "The child shall not inherit the sins of the father" (in your case mother) That way if they really are Christians they must stop "Bullying" you..
HEY CHRISTIANS AGAINST HOMOSEXUALITY BECAUSE IT IS SUPPOSEDLY A SIN IN THE BIBLE; GET PREPARED TO ALSO SELL YOUR DAUGHTER, NEVER SIT WHERE A WOMAN WHO HAS HAD THEIR PERIOD HAS SAT, DON'T EAT ANIMAL FAT, AND ALWAYS LEAVE FALLEN GRAPES ON THE GROUND EVERY DAY
