"You don't see them raising millions to register knives, or baseball bats, do you? "
No, I see them shelling out millions to outlaw weapons that result in far *fewer* deaths than knives, baseball bats, and bicycles.

The guns the prohibition lobby has been fighting hardest to outlaw for the last 25 years are the most popular civilian rifles. Look at that chart and tell me how rifles compare to knives or clubs....
They have also campaigned hard for banning guns that have been used in
zero murders in this country that I am aware of (e.g. 50-caliber precision rifles). So, yeah, they don't care how rarely guns are misused; they want to ban them.
I'll also point out that the gun-control lobby primarily targets the most law-abiding of gun owners (CCW licensees and competitive shooters),
not the people actually going out and shooting each other on the streets on a daily basis.
