Conscription to fight in a war. The assumption here is that the country owns its citizens, rather than its citizens own the country. What right, really, has any government, elected or otherwise, to coerce a person into going away to kill people who have never done harm to them, on the proviso that they 'might do harm' to them.
If a country looks like it is in danger, such as Australia when the Japanese were invading, the volunteers will come forward. But Australia sent men to the Boer War in 1899, Word War One in 1914-18 and to World War Two in 1939 - well before Pearl Harbour...because we were expected to. To me, this is a sort of insanity.
Of course, we did it out of fear: the fear that Great Britain would not help us if we were in peril. The same reason the Australian governments sent troops to support American military operations in more recent conflicts. "Gawd! We gotta do this. We might need the Yanks one day."
Military conscription, that's the law I think no government has the right to implement.
