Exclusive Brethren have pockets of adherents in N.Z. and Australia too.
Whilst they don't vote or hold political office, they have absolutely no qualms about donating substantial amounts of money to politicians who support their 'family' ideals. They don't like getting caught doing it either! Big news before the last election in NZ where they were found muddying themselves with money and politics.
Curious observation; A disproportionately large number of EB women are 'ginger' and have a certain look to them. They are very fond of long denim skirts. The men never wear ties. They avoid the use of fax machines if they can.
That's all I have to say about that....
