That is a generalization to think that guns are something that "the right" like to have and "the left" dislike.
Attitudes about guns are shaped by how you were brought up to associate with guns, as a tool, a protective item, a scary violent item or however else you perceived them to be. The politics come in later. Even most people who think you shouldn't have guns have no problem with themselves having guns, either in their possesion, or by proxy in the hands of bodyguards or police. Like many other issues, it is the fringes who capture most of the discussion and are heard the most. With guns, the fringes are those who support a total gun ban, and those who think everyone should have a gun. Those two groups drive the dialog, which is actually more about lecturing than discussion.
I am very antiwar and pacifist. I think for the most part I have no use for a gun. But I don't think I have the right to tell some person I don't know, and have no idea about the threats and dangers in their life, that I can deny them the right to protect themself in whatever way they determine to be best for their situation.
One other thing, when people get all alarmed that the government will ban guns, I think that is hilarious. I am speaking about the US government here. These clods are so inept, that if they ban guns then it is a sure bet that there will be more of them in people's hands. Look how they botch things up so badly, like getting water and supplies to disaster victims that would welcome them at the door, can a rational person think they would accomplish doing anything for people who do not want their intervention? Too funny to ponder that one.
