[Highlander] I am an ancient Celtic Druid that happens to be an Immortal. Is there any place were I can fight?

One of the rules of immortals is that they cannot fight on Holy Ground, to a Druid technically the whole Earth is Holly Ground. Does that mean I'm protected everywhere on earth and no Immortal can attack me?

The whole Earth isn't Holy Ground. For something to be sacred, something else must be mundane. So places on Earth must be divided into sacred and mundane. This means only the holiest places are "Holy" enough that the rules be followed. Sacred groves and standing stones and the like.

Everywhere else is fair game. This must be the case as it matters not who holds the ground sacred. A Buddhist may not fight in a church, just as you may not fight in a mosque.

If the entire Earth were held to be Holy Ground, there could be no Game.
