Is the Second Amendment necessary in today's society?

the right to bear arms enables one to keep and possess a weapon to defend their homes and property, essentially. guns is taken out of that by the word arms, obviously. what is instead needed is not to teach children that guns are bad, but that they are dangerous tools which need to be learned about at an earlier age so these incidents of accidental gun-related deaths can be avoided.

OT: IMO it already is in the 21'st century. though state legislature limits that, and it varies state by state, everyone in america has the right to own a firearm, anything more is excess and not protected by the bill of rights. a vehicle cannot be a firearm, because it is obvously a vehicle. that would alleviate the notion of bombs, an explosive device, and tanks. though, there also exists the rights to a peaceful protest, which is also in the bill of rights. if one feels that the government is wrong about an issue, you have every right to stand at the front gates of the white house and hold a sign up that contains a peaceful yet protestful message. so long as you do not make a ruccus by shouting, jumping up and down, or running around, the government cannot legally make you leave a public place.

You are mistaken. In the 14th Amendment the rule of incorporation was applied. All states are forced to comply with all, and any, governmental legislature. One can argue that the government grants us the ability to bear arms, but states can limit that by placing requirements. The NRA is also willing to appeal to the Supreme Court at any minute to reinforce the 2nd Amendment.

In regards to the OP, the 2nd Amendment is necessary. It allows citizens the ability to protect themselves. However, there is a laundry list of flaws that come with the right to bear arms that will some day be dealt with.
