Why play two bigoted worldviews against each other as if one lessens the other? This kind of action could have come from a number of bigoted perspectives, religious or otherwise. ISIS calls on people to carry out actions like this independently, and sometimes organises them. They are responsible, whether they knew about it in advance or not. The gunman credited them, so unless this is a very odd false flag operation, I think we can take it as given that he was influenced by their philosophy (which isn’t that complicated). The fact that anti-LGBT opinions already existed in the more moderate views of the father could also be a factor. If a disturbed individual bombs an abortion clinic and claims that this is for Christian reasons, I won’t blame all Christians, but I will blame ‘moderates’ who show tacit support for his actions, or merely say that their god will punish abortion clinic workers.
