I am a lefty from a south asian country and I think the american 2nd amendment is a great rule.

It's not a rule. That's not how the U.S. constitution is written. The U.S. constitution recognizes preexisting natural rights while imposing limitations on how the federal government can infringe on those preexisting rights.

In the U.S. the right to firearms exists without the 2nd Amendment. The 2A specifically limits exactly how the federal government can infringe upon that right.

BUT. You have a problem, and somehow you are not addressing the issue, you are just dancing around it.

The mental health issue ties with affordable healthcare and a lot of americans despise it.

I don't even think that is an actual issue. The amount of incidents out of the total population is extremely small.

So, either you have a full gun control or provide affordable mental healthcare to people. But you are against both of them. That's why this is an unresolvable issue.

Or do neither. The Constitution prohibits gun control, one of the reasons gun control is consistently struck down by superior courts. Additionally, there is no right to have healthcare provided for you.

It's not an actual issue that needs to be resolved. If we cared about lives then tobacco products would be banned as it would take over 600 years for the amount of mass shooting deaths to equal the same amount of deaths caused by second hand tobacco smoke in a single year.
