I think the only thing you can really nail down George Galloway as being in support of for a long time is the media visibility of George Galloway.The traditional far left in the UK spent most of their time arguing the semantics of orthodoxy. They were constitutionally distant from the standard extreme right wing activities (from gaslighting through harassing Muslim women, to setting nail bombs). Thehard left's most vigorous activity was secondary picketing. A very long time sine we have seen any of that - since it was made illegal.
Gorgeous George has always been an iconoclast, cherry picking issues without any balance or coherence. My impression is that he is mainly some sort of Islamist these days.
