There is a tendency in traditionally Christian societies (grossly speaking, the West) to leave behind words or expression which allude to such heritage or faith. A familiar example is CE and BCE instead of AD and BC. I'm interested here with the case of "Oh my Gosh", which is used instead of "Oh my God".
Now, according to this answer, the first time this word was used as replacement for God was in the 16th century by Nicholas Udall, who was himself a religious person (at one point he became a vicar, actually). So, although not in its origin, has the use of such word become as an expression of anti-theism? By anti-theism I mean the rejection of theism, not confined to but exemplified by atheism.
