It is risky to remove symlink targets! Imagine there's a symlink to /etc ...!
The following checks the link target to have at least two /. But e.g. a link to /etc/passwd would still delete /etc/passwd.
Code:
find my_directory -type l |
while IFS="" read -r fname
do
  ltarget=$(readlink "$fname")
  case $ltarget in
  */?*/?*) (cd "$(dirname "$fname")" && rm -r "$ltarget");;
  esac
done
rm -rf my_directory
