When we find the tomb of Jesus, why do we apologize to Christians?

There is so much soft-stepping about this idea...why? When new evidence comes to light about a scientific idea, the idea is quickly updated, no one cries, and the world is a better place. Now that we have found what might be the most important religious artifact in the world, Christians don't want it to exist, and archaologists are practically apologizing that they found it. Why this excessive consideration for theists desire to be continually deluded?
