There should be a "It depends" choice in the poll.

I believe the intent of the tattoo determines if it desecrates the body or not.
In regards to decorations, items such as jewelry, cutting one's hair, and nice looking clothing (not excessive, just nice) could fall under the same category of implying to God that His creation of us was not pretty enough. We have a tendency to dress our bodies up.
I see nothing wrong with tattoos. Tattoos are a decision that must be taken seriously, and our ability to testify should be taken into account. There are some that would be turned off by tattoos, while others would be more accepting of a person if they have tattoos. I have seen both in my personal life.
The content is key, as well. My wife has two tasteful cross tattoos. I have none. My wife is a very devout Christian, and serves God in her work as an artist, in the church and in the community. I have seen people react uncharitably to her tattoos, which to me highlights their weakness in the faith than anything else, as I know of her dedication to Jesus.
Regardless of your personal view of tattoos, I would encourage people to not judge "the book by its cover" when it comes to people with tattoos. The intent of the tattoo says more than the mere existence of a tattoo.
In Christ,
