I haven't asked you to justify the current gun laws in America, nor have you done so. You're participating in a thread which about yet another mass shooting in America. I would have thought the "why" was rather obvious, but apparently you don't.
You're not remotely interested in changing the gun laws, yet you keep straw-manning others' arguments into "they want to take away our guns", which means you're not interested in discussing others' viewpoints, only your own being "let's do nothing about gun control" or an extreme opposite (which you cannot possibly believe is the right thing to do), which as I said already, no developed country I'm aware of has implemented.
Don't claim that what you want is an end to evil/sick people using guns to hurt others while simultaneously advocating doing nothing, because that is just plain hypocrisy.
And?
All you've done here is consign yourself to a group of people on this forum who are only interested in talking about their own opinion. You've responded to me twice yet the only point of mine you've actually responded to is when I stated that I can do in the UK what you stated that most American gun-owners want to do yet mass shooting here are rare, and your general opinion appears to be, "but it should be easier" with no practical justification as to why.
Now to use your own straw-man argument against you:
Not to mention the fact that your latest post makes no sense: you advocated a number of measures which would restrict gun ownership for people who may be a risk to others, but as you say, there is no way to see into the future and tell us who will misuse a gun, then you go on to say that you're not willing to remove constitutional rights for any amount of perceived safety.
I also find it interesting that you used an expression "who have no business owning guns", yet your "business" for owning firearms is apparently "target practice and a bit of hunting", and don't forget: "FREEEDOMMMMMM!".
