The KKK / Al Qaeda parallel is apt I think. However unfortunately the Muslim world has allowed themselves to be defined by their KKK. That is the difference. You are right to get angry about it but that’s what has happened.
The reluctance in some cases, slowness in others, to condemn and capture the Al Qaeda and Taleban etc by number of principal Muslim countries is what led to the lack of trust when such condemnation comes ultimately.
Regardless of why it happened, given that it has happened, the whole Muslim world has to dig its way out. As that happens, incidents such as the qatarian idiot simply makes the process more difficult than it has to be.
Sometimes it is easier to alter reality than it is to change perceptions!
