The extreme anti-gun people and their followers in Wisconsin are very frustrated. Many of them really believed the stories they were told about frequent "Shootouts in bars like in the Old West" and "casual arguments and disagreements turning into gunfights". These anti-gun extremists were shocked that these predicted events were not happening here, and they didn't happen in other states either.
Incidents of senseless domestic violence, which tends to escalate despite restraining orders, has been around for centuries, even before firearms existed.
Same for racial hatred and violence, it predates Holocaust/Serbian/Rwanda/Darfur ethnic cleansing/genocide, the Ku Klux Klan, and skinheads, and has involved everything from machetes and lynchings to gas chambers and firebombs.
Neither of these is caused by guns, nor will the absence of guns stop it. We would need to eliminate gasoline, kitchen knifes, baseball bats, fists, etc. Not gonna happen. We need to punish criminals and criminal behavior, not tools.
Until that happens, being trained and equipped to protect yourself and those near to you, and avoiding places that restrict that US 2nd Amendment right, is a good plan.
