How come we deem some celebrities' baby names as "strange" and similar ones "normal?"?

I remember when Gweneth Paltrow named her daughter Apple, and I thought it was the cutest thing in the world. Many other people thought differently. I heard a lot of “who names their kid after a fruit!” But what if she had named her Brandy (liquor) or Olive, or Ginger, or Candy, or whatever else… would it have been as big of a deal?

Would your opinion of the name “Apple,” for instance, have changed if it was a child in your kid’s school, or someone you had just met instead of a celebrity?

Also, I suppose my question could apply to non-celebrity baby names as well. I guess I just don’t get why people have such distaste for any uncommon name.
