I’m just happy that you’re admitting that “responsible gun owners” would become domestic terrorists if democratically decided laws didn’t suit them and police selectively enforce laws and procedures.
I guess they’re not “good guys with guns” after all but violent, political extremists who are one inconvenience away from killing innocent people and wow, doesn’t that lens bring the last 25 years of pro-gun policy into a sudden, sharp focus.
Anyway, you’ll have the same options as everyone always does when laws like this change.
You can surrender any illegal weapons, admitting that you never actually needed them and all of your flowery, self-aggrandising rhetoric was nothing by role-playing.
You can undergo the background checks, take the safety courses, register your weapons, wait through a usefully long waiting period, store your guns securely and accept that you’ll lose your firearm rights if you hit your wife or have your gun recovered in a crime – things that you could have done at any point, but chose to let people keep getting killed by legal gun owners instead.
You can hide your illegal guns away, unable to take them to ranges, show them off on the internet or point them at your wife because if you’re ever caught with them, congratulations, you’re now a felon and are no longer entitled to your gun rights anyway.
You can become the next Maine shooter in a bizarre attempt to convince the country that you should have been allowed guns with minimal oversight, optional safety and widely published loopholes.
Notice how there isn’t a single way out where you’re not a piece of shit?
That’s because gun owners who fight to preserve a clearly flawed system are pieces of shit, just like the people who fought to keep slavery, or keep segregation, or prevent women voting, or keep homosexuality illegal or any of the other morally bankrupt things the right-wing has rushed to defend.
