Some false
assumptions here.
Then, you mentioned that no guns in domestic disputes = safer. Again you're implying that gun owners are more likely to commit murder in domestic disputes, than say, kitchen knife owners, or baseball bat owners. Hate to tell you but that is completely false. As an example, the Ontario Office of the Chief Corner did a report on Domestic deaths in the year 2008 for the province of Ontario:
http://www.crvawc.ca/documents/DVDRC...28FINAL%29.pdf
and found that 27% of deaths of women were caused by stabbing, 60% were "others" (choking, hitting, etc), and 13% were by gun shot wounds (table 9, page 13 of 51 in the PDF). Meaning, women are twice as likely to die from knives (of any kind) in domestic disputes, than by guns. If you look at the 5-year number, deaths by gunshot wounds is nowhere near as common as stabbing deaths. Check out Table 4 on page 11 of 51 for another stat for the years 2002~2007, where 34% were stabbing deaths, a combined 45% for stragulation/other, and 21% shooting deaths.
In the heat of the moment, ANYTHING can be used as a weapon to hurt the other person. Your statement of "guns at home = more deaths during dispute" is completely false, and is supported only by perception generated by the media (anytime a gun is mentioned, it's bad news), and not by facts. I can google more official government stats for your viewing but you will only see more of the same numbers.
Lastly, I do agree with you that gun control doesn't work to protect us from criminals, and the ironic thing is that IF you had the ability to carry firearms with you, the likelihood of you being a victim can be lessened. Handgun ban lifted in Washington and Chicago = crime rate went down. Prior to the ban being lifted? Both had some of the highest violent crime rates in the USA.
Look, I'm not trying to tell people that they're wrong about how they think of guns and gun owners, but sometimes it's hard to argue with facts when they are so blatantly obvious that objects should NEVER be the center of attention in tragedies like the recent shootings.
