I am pretty left of center myself, and quit the NRA over 20 years ago.
Wig is right ... the genie is out of the bottle. Taking guns out of America would be like taking fish and chips out of the UK or moose out of Canada
. It's a part of the lifestyle or culture of a large segment of the population, the vast majority of whom are perfectly law abiding and not a threat to society in any way.
When it comes to kids and guns in the house, you have to consider the kids, too. If your three year old has already learned how to pick the child locks on the upper cabinets, you might be well advised to be a little more cautious than if Johnny or Janie almost always does what you tell them.
I find the arguements of those who would ban all guns as simplistic as the arguements that guns in the house are no different than knives in the house. I find most of the arguements against registration fairly weak as well ... the paranoia of those who envision "a knock on the door" (probably after survellience by black U.N. helicopter) suggests a mental condition that would suggest gun ownership is probably not appropriate for that individual, IMHO.
