@BillW,
And these retweets are now the reason of an extraordinary diplomatic spat between the transatlantic allies USA and UK, because Trump has publicly rebuked Theresa May over her criticism of anti-Muslim propaganda and supporting a British far right hate group.
But at least this extreme far right, pseudo-paramilitary neo-Nazi group got now worldwide attention.
[As an aside: Britain First was initially supported by James Dowson, a former Calvinist minister from Northern Ireland who has expressed support for Mr. Trump, President Vladimir V. Putin of Russia and Britain’s vote to leave the European Union. But he parted ways with Britain First in 2014 over its tactic of "mosque invasions".]
