If you are going to abuse something sacred it is far better to use it for no particular purpose than to use it to directly fight against God and destroy his children.
To use Christ's name as a swear word is revolting. President Kimball, hearing one person do so said "That is my Lord's name you revile". But it is far worse to say that because you follow Christ, you stand by immorality. One is taking his name in vain to accomplish nothing. The other is taking his name in vain to destroy his children.
If it is offensive to use his name as a swear word that means nothing at all, how much worse is it to use his name to profess that his mercy requires that we tolerate, endure, and embrace sexual sin.
