Registration leads to confiscation. He replied that a background check isn't registration. I explained that, yes, the dealer keeps the paperwork and it's not sent to the gov, but what's to prevent the gov from kicking in doors one day and confiscating all of these records?
The "slippery slope" argument. What's next? Fingerprinting or DNA samples in order to buy a gun?
Criminals don't do background checks, so what's the f-ing point?
And like you wrote, "fuck the man, that's why". The gigantic balls required to tell me that I can't give my son a gun....huge f-ing balls.
