Well, you are wrong. That is, unless you are a constitutional scholar with powers the supersede those of the US Supreme Court.
In "Heller" (2008), as the case is generally known, the US Supreme Court explored the history of the Second Amendment and established that it creates an INDIVIDUAL right not linked to a militia or army. This was confirmed once again by the US Supreme Court in another case in 2010.
There's a popular meme that involves cutting-up pieces of the Second Amendment to pull out, as you did, "right to bear arms" and "well-regulated militia" and then, Bob's your uncle, you can't have a gun. Everyone is a constitutional scholar. Well, that's not how it works.
While IANAL, I understand that these things are the result of a process of legal challenges and a lot of historical context. This question of the individual right is now very well established with, as far as I can tell, just a few corner cases. Thankfully laws are not interpreted by random people behind keyboards at random locations on the internet. They are the result of years of legal process, challenges and interpretation. The law, as it stands today, says you are wrong.
In other words, it is pretty much nonsensical to keep trying to contort the language and claim something exactly opposite what the US Supreme Court concluded in more than one recent review of the matter.
Here's a good article on the matter from Cornell Law School:

I have a lot of friends who are very passionate and well informed about this stuff. I've learned quite a bit over the years through conversations with them. For the most part what I have learned is that most people don't know what they are talking about when it comes to the US Constitution, the legal system, how government works and even what their rights actually mean.
It's a failure of, at a minimum, our educational system and, at the modern extremes, our inability to prevent the dissemination of false information. That's how you get ideas such as the "assault weapons ban" when any objective observer can easily --within 15 minutes or less-- of looking at the data, conclude that's as dumb as clipping your toe nails to cure cancer.
Solutions are only found if we explore reality, not fantasy.
In other words, nation-wide gun bans and confiscations are not the realm of reality. Therefore, it is pointless to go on and on about this nonsense. If we want to truly have an effect on gun violence we need to stop focusing on fantasy and face reality, which includes bad guys with guns and mentally disturbed guys with guns. The vast majority, the overwhelming majority of firearm owners would never hurt anyone. They are not the problem.
