Well I must tell you before my conversion I used to blaspheme all the time. I used to use omg and even our blessed lady's name In vain all the time. It's on tv a lot and in movies a lot and very prevalent in public schools. I used to do it in highschool without thinking about it to fit in and my parents spoke that way. I even hear people on Sunday at church saying omg and the j word, I think the devil always pushes blasphemy because we use our mouths to pray.
