While Loop Issue

Sooooo Unity continues its streak of lets confound this noob once a day. Simple Simple test code, heres its purpose: 1) Game tiles are created in a scrollable list. 2) If another menu category is selected I need to clean said list. I do so by destroying the created tiles 3) Easiest way to do this is a while loop knowing the sibling start position and the number that should exist at the end Heres code 1 from my test button (which means I hand jammed some values, its just easier then executing the big code every time)

 public void  OnPointerClick(PointerEventData data)
     {
         int x = 17;
             while (x > 10)
         {
             Destroy(GameObject.Find("Menu").transform.GetChild(1).gameObject);
             x--;
             Debug.Log(x);
         }
     }
 }

This code executed correctly once, I smiled (big mistake), and it hasn't executed correctly since. (restarted program and all) (Worth noting the time it worked I made x subtract with x=x-1;)

Also this would have been the shortest way to write this loop, why does this freeze the program?

         while (GameObject.Find("Menu").transform.childCount > 10)
         {
             Destroy(GameObject.Find("Menu").transform.GetChild(1).gameObject);
         }

Wouldn't the act of deleting a child change the childcount? On an off note I think I found the cure for low blood pressure.
