Dude, on the real, you need to go wash your pussy, and then learn. Guns don't cause crime, criminals and overzealous government does. Outlawing guns won't do shit except maybe embolden the Mofo's who steal, rob and worse. Places that had high gun crime prior to arms bans still had high gun crimes after the ban. England has almost double the gun crime than before the 1997 gun ban. Cops are more likely to carry guns now than 100 years ago, when having a gun in the house was very possible.
Now onto the reason we have the 2nd Smendment here. It has to do with balancing the power of the people vs. the State, and the Militia. First, in order to help keep the Govt. from getting out of pocket, every house became a potential pillbox, and every town became a potential fort when there are guns around. Second, until after WWI, most of the troops for a war came from state militia, and they often had rifles as well. Also, many thought there would be foreign invasion, and once again, every house became a potential pillbox.
Now, was there a specific discussion about personal defence, no. There did not need to be. It was understood to be a personal issue. But there also was no specific discussion about Abortion, Miranda rights, Welfare and a host of other "rights". But they exist.
I always get pissed off when other people come up with ideas, and think that it would be good to subject others to them, just to make themselves feel comfortable. Fuck that. I should not need permission to protect me and mine, especially when those who would be in charge of doling out that permission usually have armed guards themselves.
