Again, it is not what we think about Ahemdis; If they consider themselved Muslims, quote the Qur'an (along with ahadees) in their support, then let Allah judge them. Alternatively, visit their websites to try and learn what makes them click. Don't agree with their interpretation? Fine, counter them with logic and discussions rather than takfeer and bullets.
At the end of the day, we all are responsible for what we believe.
