Temper! temper! I have come to the conclusion that a great deal of the unpleasantness is caused by the high anger levels of the main posters on the political threads spilling over into ALL aspects of GN. They are so fired up to fight battles that they just can't stop. I really think that if it were physical combat they would follow someone into A&E to keep the fight going, and complain bitterly to the staff that their rights were being eroded because the patients had mentioned where it was they came by their injuries.
SK is an A&E sanctuary. People go there to get plasters on their cuts and arnica on their bruises, and recuperate. It is not surprising that during the treatment they sometimes mention the cause of the damage. They don't go on about it, they accept the calm atmosphere and cool down.
Advice to stay off the political threads? It is impossible to avoid, not the threads but the posters who fill threads on all subjects under the sun, claiming that "everything in life is political". Well, A&E is one place where patients under treatment are allowed to be non-political - or even anti-political if that is where their injuries were sustained. They'd be anti-car if they'd just been in a road accident, even if they had not been driving all that well themselves.
