Re: Because
Are you trolling? The US constitution is very clear that the purpose of the right to bear arms is associated with being part of a militia.
"A well regulated militia, being necessary to the security of a free state, the right of the people to keep and bear arms, shall not be infringed."
Its as relevant to modern day society as the local laws about having to take part in archery practice in certain parts of the UK. I put away my toy guns at age 8 and grew up. Would be good if you lot did too.
