The English Lobby - Talking Gobbledygook

From the English Lobby site:

For decades since the 1950s, England as a nation has been largely ignored, and use of the words 'English' (as applied to its citizens) and 'England' (referring to the nation) steadily declined. This trend continued throughout the 1970s, especially after law relating to discrimination on the ground of race, ethnicity, nationality and national origin was increasingly enforced in tribunals and the courts in the 1980s and after.

Hang on.

"This trend continued throughout the 1970s, especially after law relating to discrimination on the ground of race, ethnicity, nationality and national origin was increasingly enforced in tribunals and the courts in the 1980s and after."

So, this trend continued throughout the 1970s, especially after things which occurred in the 1980s and beyond? But surely the "1980s and after" came after the 1970s? Surely "this trend" couldn't continue throughout the 1970s as an effect of events in the 1980s - as the '70s had ended before the 1980s began?

Is this another "let's mention the 1970s for God's sake" type comment, which renders the rest of what's written complete and utter nonsense? The Web is full of them.

Surely it SHOULD read:

This trend continued, especially after law relating to discrimination on the ground of race, ethnicity, nationality and national origin was increasingly enforced in tribunals and the courts in the 1980s and after.

Sorry, English Lobby, it's my first look at your site and I have to say I find this type of thing disappointing.
