I have no problem with the stated intent of background checks, but in practice I don't see how we can be assured our rights won't be infringed if we submit to one.
The problem I have is that there's no way of knowing that once you've confessed to the government your desire to be armed, they'll forget about it when it's no longer any of their business (not that it ever was in the first place).
On the other hand, if 80% percent of the public falls into that category, it's probably a GOOD message to send the guvmint.
Problem #2 is this: If 2A was intended to protect us from a future tyrannical government, how can we put the government in charge of deciding who can be armed?
Submission by a citizen is infringement. 'How can we put the government in charge'? We can't. The 2A can be infringed only by a tyrant
