Is your legal theory that any technology which is dangerous should be protected under the second amendment, simply because it is dangerous?

No, my legal theory is that you cannot simultaneously compare technology to a weapon and also say it falls outside the bounds of the 2nd amendment.

Dual use does not mean weapon. And even then, it is simply not the case that all weapons fall under the second amendment.

a tactical nuke is a weapon to which the second amendment has no applicability
