The experience of the German people just 90 years ago should help us understand the beauty of the 2nd amendment and the contrast between a militia and individual rights.
Germany had a well regulated militia and also enacted laws that prohibited Jews from possessing firearms. It was through required registration that the Nazi government knew which Jews had firearms. Prohibition was extended to anyone who wasn't political reliable with the penalty of death.
Germany in the early 1930s went through much of what politicians in Washington DC are proposing in Washington now. And with the same promise that it's for everyone's safety.
