No Muslims in the region are 'good guys', let's get real...
Most of us have the motto, 'Let them kill each other, it keeps them from killing us'. I understand this...
But in truth some muslimes are better and some muslimes are worse, they are not the same. It is hard to know which ones are more trustable, or less trustable.
As far as fighting ISIS goes, America has used them as a crutch to fight our war against ISIS. In truth we should not pull out without making sure they are safe, lest it inspire more hatred causing them to align with other more vile muslime regimes.
