In Leviticus 22:32 we read: “You shall not profane My holy name, that I may be sanctified in the midst of the Israelite people—I Adonai who sanctify you.”
Is saying, “oh my G-d” in casual conversation really a way of profaning G-d’s name? If profane is the opposite of sacred, then isn’t anything casual, by definition, profane?
On the other hand, G-d isn’t really G-d’s name. What do you think? Should we try to remove this common idiom from our speech?

Respect for all of creation is pious – whether its formal or casual, in word or in deed.
