Let's see....
Liberals want legislation that prevents people with psychological illnesses from owning guns.
Conservatives say that liberals want to take their guns away.
Think about it...
What does that say about conservatives?
That we are intelligent enough to realize legislation won't stop anybody from getting a gun if they really want one????
Another conservative suffering from paranoid delusions! By the same logic, we should not have any laws!
Does the fact that murder, arson, rape and robbery happen despite that fact that we have laws against them mean that we should not have those laws?
The fact is that like those other crimes, having laws that prevent psychologically ill people from owning guns will severly reduce the instances of guns crimes being committed by those people.
Like those other laws, it would not make a perfect world, but using the perfect to undermine the good is no answer.
