Oh, ffs, on your understanding of national news, we would never hear anything whatsoever of what happens anywhere else in the UK - on your logic, floods are only relevant to the people flooded out, the Scottish Highlands are relevant to virtually nobody, murders are only relevant to the local community...
If your understanding of the Southern Rail Strike is merely that a few commuters have been annoyed, today, then clearly the problem is that the real news has not been reported enough, or you wouldn't sound so bloody ignorant about the issues involved. The BBC has done a lot more in depth reporting on the issues involved than you describe, in any event, so I'm not sure how you managed not to be aware of the wider implications. Problems with Southern Rail have been going on for years, but have come to a head in the last year, particularly since the summer, when it genuinely did start to have national implications, and it's a hugely political, financial and 100% obviously national issue, not a little local bother that won't affect future policy, legislation and industrial relations. And it does affect the national economy, too, and tourism. It has so obviously become a national issue as it has dragged on and on, that your inability to comprehend that just comes across as ridiculous, petty and ill-informed, not over-informed.
Feeling cross.
