Something tells me that the Afghani who blew himself up, or herself up, at an education center along with 48 other people, well, it’s extremely unlikely that person was a member of the Afghani government or military, nor the U.S. government including its military, nor NATO military. It’s a safe bet that most, and perhaps all, of the dead were fellow muslims.
The killing, the violence, the subjugation of women, the subjugation of non-believers, the racist belief in superiority of their group, their expressed intent to dominate others, these and more are serious objections to muslim immigrants or refugees. It is not their religion or their god that is objectionable. It is their actions towards other people, even against their own people.
