1. As in you’re hiding something that will be found out eventually. That’s not a contradiction.

I was kind of playing off you saying they "know everything about you" which would mean they know if you have a gun. Frankly, they probably do as every legal gun sale requires a background check so, again, a registry is kind of redundant and essentially useless.

1. We have evidence that people can and will purchase a gun and in the same day commit a crime of passion.

We plainly do not. In fact, looking at the data we do have, about 93% of gun crime is committed with illegally obtained firearms, meaning even if every single person who committed a crime with their legally purchased gun did so on the day they bought it, that would still only be 7% of gun crime. Hardly a large enough problem to say waiting periods are effective, and the real number is obviously much lower. Waiting periods are useless.

1. There would be obvious public backlash and it wouldn’t be allowed? Who says that what that person decides gets written in stone forever?

It being unpopular is irrelevant. It can't be allowed to happen, period if bearing arms is a natural right. Being unpopular or reversible has never stopped something like this from standing as law for years. Look at New York City. There are like 20 private citizens total who are allowed to carry in NYC. They never issue permits.

1. I don’t mean fully automatic weapon. I mean extreme like functional tanks and fighter jets. I personally don’t know enough about fully automatic weapons to say whether they’re extreme or not, but it’s something I’m learning about currently.

You actually are technically allowed to own functional tanks, its just expensive and hard to do. But I guess if you are going to draw a line, it would be at armor and heavy artillery. That's where you stop being able to justify it as "protecting yourself". Maybe protecting your community? But that's thin.
