If you believe, as I do, the 2A is rooted in codifying the ability to take up arms against an oppressive (gun-restricting) government, as had just been done a few years prior, you're out of touch. If you believe in gun ownership for protection, you're going to accidentally shoot your child. If you believe all guns are bad, you're point of view is to be enforced at the business-end of a government-owned gun.
It's all madness. Try not to form a view of the argument from Reddit.
Case in point?

(hint: it's very divided - somewhat by age, but not enough to back up my original point)
The most depressing one to me is the divide between registered voters (slightly pro-gun) and non-registered voters (heavily anti-gun). If you want political change, maybe try voting!
I don't know what country the parent commentator is from, but US states are the size of most countries. At a local level there may be vigorous debate, but the only other comparable governments are the EU and maybe China. I imagine that the citizens of those governments also feel like they have very little voice?
(edit, the EU is not a country)
In short, they understand guns, but not computers.
Young people grew up with the internet and are better informed, but they have no control. District lines and campaign financing have made it impossible to make an impact.
The numbers are reaching a tipping point though, and you should expect to see a very different America in the next decade or so.
