I thought the inference was that he was a jihadist. Hence the references to " terrorism " ( however lame ) ?I will use Islamist to mean an adherent of Muhammad. He was a political leader who used religion to get others to die in support of his causes. If there is such a thing as a moderate Muslim, which I doubt, then an Islamist is not one of them.
That he was a recent Muslim convert imo doesn't imply that he was a jihadist. Just someone who had lost the plot and just so happened to be a Muslim
