I disagree. If you don't believe in "shall not be infringed" then you are on the other side of the fence.
Exactly. There is no middle ground here. A person either believes our right to keep and bear arms "shall not be infringed", or believes it MAY be infringed in whatever manner the government decides is "reasonable", which is a subjective term ripe for abuse.
I have -zero- respect for anyone who believes in the latter, and am ashamed to call them my countrymen.. I wouldn't whizz in their mouths if their stomachs were on fire.
