Suppose we fix your voice box so you can't yell fire (can't own a gun). That way you will never yell fire in a crowded theater (use your gun irresponsibly). Sounds reasonable to me. If you spot a real fire (see a crime happening), you are to call 911 and report it in a normal voice. After all, it is not your job to try to help in an emergency. That is the government's job.
Do not confuse the right with the responsibility for outcomes when exercising that right. Free speech must have limits as to use; just as you can't say any thing you wish any where and any time just as the press can't publish anything it wishes and citizens can't assembler any where at any time, gun owners can't shoot any where at any time. The restrictions are on use of the right, not on the right itself. Big difference.
