Yeah, good luck with that.

That "right to bear arms" thing was written a long time ago under very different circumstances, I don't think it applies in a modern and civilized world. Guns are something for movies and games, but in real life, it's wrong man.

Considering in Brazil almost everyone is prohibited to own guns but all criminals have it, some even anti-tank, RPGs and etc... and that is extremely easy to buy guns (illegally)... the talk about only selling to people that are mentally health doesn't hold much, those guys would simply buy illegal if necessary...
People that buy illegal are the most likely to commit crimes anyway.

Well that's an entirely different problem. I think you will have a hard time buying an RPG in most Western European countries or an anti tank rifle. Hell I would not even know where to get a simple pistole. But I agree that if illegal guns are very easy to get gun restrictions are not much more than a piece of decorative paper. 

Although I still do think the US should have accepted Obama''s gun acts to at least forbid weapons which are intended for war and slaughter instead of self defence. Especially in rural areas with puma's, beers and wolf's I could get behind the reasoning that you want to own a gun.

In the USA, you can go and buy 40 guns with no questions asked, but getting health insurance is like solving the mathematical equation for Sephiroth's Supernova.

Since guns are carried by people and people are a part of society, I don't see how those problems are uncorrelated.

Buying guns and buying health insurance are about equivalent in terms of difficulty, but the obstacles are different. Questions are asked in both cases. If you buy a gun in even the most gun-liberal (liberal as in lenient laws) states, you need to pass a background check or hunt down a private seller who will sell to you. Private sellers aren't as ubiquitous as some people make them seem. You can find a few at a gun show, but the nearest gun show to you might be an hour drive away and only is held once every few months. You might be able to find one online in certain states and set up an inperson meeting with them, but that is pretty rare too. Overall it is likely easier to just pass the background check or buy a gun illegally than to find a private seller with what you want. This is why most illegal guns used in crimes are stolen or supplied by gang members, not legal private sellers. 

To buy health-insurance you need to go to the ACA marketplace (or directly to the insurance holder) put in information about yourself, and then find the plan you want. Like buying a gun you will shop around for the plan you like the best. 

 

I am not for guns, but I believe in self defense and I am not very fond of tyranny, therefore, I need guns.

If there was a universal way to help people with mental health that would bring mass shooting crimes way down. Most people with a mental illness are not harmful and many seem somewhat normal but there is that small few who are dangerous and the mental health care in this country is a joke. It would not stop these crimes but it would greatly reduce them. As much as I hate guns, getting rid of them isn't the issue. If I recall Canada gun ownership is equal to that of the US but have much lower gun crimes. Criminals will get guns legal or not if they want.

Gun dealers are all over...

You know that most illegal gun in Brazil is from USA procedence right? (Our sole big manufacturer is very bad so only our police uses their gun). So if Brazil not producing RPG locally we have a lot of drug lords with those guns in here and drug is sold even in Europe you can be sure if drug lords over there wanted RPG they would buy them. They probably don't buy because the fight for power and defense against the state over there isn't on the same level as here since there is no regular criminal using RPGs to assault you.

The only reason you have to give the state to having a gun is "I want it".

A registered gun is very seldomly used on criminal ways (unless robbed), while illegal is all the time, and where do those guys get those guns?

The only country I know that really have about 0 illegal or legal guns is Japan because of a very tight control over everything, being insular, too crowded, etc. In a country as big as USA that kind of control is impratical, in Brazil even more.

So the guy can buy an illegal weapon and use for crime against a defenseless citizen or the citizen may have their gun and criminals be less prone to rob them.

And in the case of the shootouts in USA, most are in gun free zones (some say 98%)

And how is that not hard??? Have illegal guns become 0 in other countries besides Japan? Drugs as well?
