Why do you want nutjobs voting in elections, running for office and driving 70MPH towards you on America's roads?
None of that resulted in 35,000+ dead from guns last year.
Why are you so hypocritical about requiring mental health exams for guns, which you don't use, but not for those things you do use like voting and driving?
Because 35,000 people didn't die from casting a ballot or driving their car last year...and 40 years ago, car deaths used to be double what they are today.
The reason they're not as high anymore is because of federal laws and regulations to make them safer.
But federal laws and regulations can't make GUNS any safer. So you have to look at who is using the gun in an unsafe way, and you've said that mentally ill people use guns in unsafe ways.
So how do you prevent mentally ill people from getting guns if they're undiagnosed?
You haven't been able to answer that question, either because a) you don't think mentally ill people should be prohibited from getting guns, or b) you just haven't given this enough thought.
I think it's "B", but I'm happy to hear your argument for "A".
