Keith A, there may be an element of truth in your comment:
"And I remember that everyone on the mainland sympathised with and supported the NI Civil Rights movement. A couple of years, months even, and public opinion would have forced the changes you are now anticipating".

But how come public opinion didn't force those changes anytime during the long years between the 1920s & the 1970s?

The fact remains, that successive British Governments for over fifty years, were well aware that discrimination & jerrymandering were rife in NI, and they did nothing about it.

Having said that, this in no way excuses murder or terroriosm by any group, which is something I condemn without exception.
