As you would expect, British and American reactionaries have plenty in common. Both are intensely suspicious of foreigners and oppose large scale immigration. Both long for a mythical period in the country’s past and want to stop the clock at that point. Both are extremely proud of their country and its history, in spite of its mixed record, and view political correctness as an affront to themselves and their ancestors. Finally, both groups are disproportionately old.
There are differences, however. British reactionaries are unlikely to be fundamentalist Christians. Their hostility to foreigners is slightly less tinged with racism. And, unlike in America, British reactionaries can be found in large numbers in both parties; they just look backward to a different golden age.
One other major difference: I would much rather spend time with a nice old lady in a cathedral than a guy driving a pickup truck with a Confederate flag and an NRA bumper sticker.
