Well, it is the Star Of David
Not to be confused w/the Pentacle or the Pentegram
The difference between the symbols is:
The Star of David has Six Points.
The Pentacle has only Five Points
And the Pentagram is an upside down Pentacle basically.
Now I bet you're wondering why...
If Taylor and his family is Christian,
Then why would he wear the symbol of The Jews?
The Star Of David on a Christian person can mean diff. things:
1. To show he was once Jewish, but has coverted to Christianity.
2. Their ancestors were Jewish.
3. A friend had given him the choker as a gift.
4. He just simply liked the look and decided to wear it.
5. Or he is honoring the fact that Jesus was once Jewish.
