reason not to try...as evidenced by the long road travelled for the Civil Rights and Voting Rights bills...nonetheless, I like that you envision changes for a better life in America.
As for the points you raised, i wouldn't be so quick to refer to .223 ammo as "BBs"...see the linked comments from someone who has to treat gunshot wounds...Assault Rifles like the AR-15 were not intended for Elk...the weapons were designed to kill and maim People...and with the .223 they do this very well...please admit the obvious....here is an excerpt that underscores the statement...
-----------------
"Furthermore, while all rifle bullets have this capability, the ammunition used by the AR-15, a .223 Remington cartridge, travels at approximately 3,000 feet per second and causes a significant cavitation effect — where a bullet is travelling so fast that it sends shock waves through the body and severely damages or kills displaced tissue."
-----------------
I'll say it again, AR-15s and all other Assault Rifles are weapons of war...that is their purpose...not hunting...not target shooting...not close in home defense...ban them like we did before.
Note once again...Australia did this very effectively...certainly the U.S. can show as much intelligence and courage as the Aussies.
