[ryuurui]

They were brought up practicing 習字 not 書道, these are two very different things. They call shodou shuuji and that is simply wrong. Shuuji is a subject you can learn, where shodou is a way of life you learn from. 道 is a key word here, which points at a "way" or a "path".　

Many young Japanese can't even write by hand 常用漢字, let alone understand calligraphy.
