Rant Time

Alright, time for a quick little rant:
A very common form of cursing in this day and age is taking the names of deities in vain. In America, this is commonly done in the form of God or Jesus Christ. Many people are of the opinion that this is not a form of swearing at all (likely due to the shift towards atheism in our mainstream culture). This has never sat right with me and here is why:

If you don't believe that taking the Lord's name in vain is swearing, then you don't believe in the commandments.
If you don't believe in the commandments, you don't believe in God anyway.
If you don't believe in God, then what is the point of using his name for cursing?

This paradox really bugs me. If it's not swearing to you, then why say it? No one has ever has ever given me what I felt was a satisfactory answer. And that pretty much bugs me.
