It depends. If you are burning the cross in order to intimidate or threaten a person or group of people, then yes. However, the First Amendment allows people to burn crosses as "protected speech", as long as the intent is for a political point. There is still debate as to how to qualify a political point over intimidation. In Virginia they banned KKK members from burning crosses.
If you are doing it just to express your freedom to burn something symbolically just because you can, you have every right under protected speech.
There are however no laws against burning the Star of David, or X's that I'm aware.
