Yes, what people need to understand about the history of British unions is that they effectively shut down the entire country repeatedly to try and force the Government to keep coal mining which wasn't viable anymore going. That's basically intolerable in a democracy. Thatcher's breaking of the unions only happened after previous governments who thought the unions could be negotiated with were brought down by their inability to deal with the damage being done. (There's also some impressive double-think on the British left around this and global warming, since of course dealing with that means that coal mining and use has to go away.)

I assume you agree with my general analysis of the unions effect on Britain?

Why interesting? I simply decided to call you out for calling for the murder of union members.

It was before I was born and I don’t have much of an opinion. I do have a very strong opinion that nobody should advocate the murdering of union members, though.

None of the 11 definitions offered by google mention the murder of people, maybe your confused?
