"It's all people who hate guns"
According to you. And that is why this discussion is so lopsided. Facts are dismissed with 'it's all just people who hate guns'.
It is not.
"Every report of gun violence in the US makes me glad for our very restrictive gun laws which give Australia one of the lowest rates of gun homicide in the world. "
The US has a gun homicide RATE (not count, RATE) that is 14 times higher than Australia.
But it is hard to compare countries, and ineffective gun control laws are not exactly the same as effective gun control laws.
For example, The VA Tech shooter, despite a lengthy history of severe mental illness and being adjudged as a 'danger to self and others' was able to get hold of enough weaponry and ammunition to create a gigantic blood bath. The 'Brady Act' in Md did not stop a severe shooting there, either.
It is not clear to me that 'effective gun control' = 'any gun control'. A closer examination and study of existing state and fed gun control laws and how they compare in what they are and how they are carried out is probably a good place to begin.
The stats on gun ownership bear out that this is not just a political (party) issue but also a regional one.
