Tongue in cheek it was. Though I don't know if you are an authority on what is blasphemy or not.
I'm not an authority on what constitutes blasphemy, but the Holy Bible certainly is. Some people recognize the authority of God's holy inspired Word, and others do not. As I said before, you are free to do as you please, but don't be fooled. According to the Holy Bible, taking the name of God's only begotten Son in vain is blasphemy.
