No right is absolute. In fact, the Second Amendment arguably has fewer restrictions on it these days than many of the other first ten, and there is and should be no guarantee that things are going to stay that way.
The FAIL positively screams at you from that blog post.
The Third Amendment (quartering troops) has no restrictions.
The 1A right to petition has only one or two court cases against it as far as I know.
The 9th Amendment (rights not enumerated) was a dead letter until the 1960's, when courts started finding rights and
expanding it!
The 10th Amendment (powers not delegated) is but a shadow of itself, and an awfully thin shadow at that, states rights being all but erased.
The 6A right to counsel was
expanded for indigent defendants so they could 1) have an attorney paid for by the state, and 2) have that attorney present even during custodial police interrogation (
Miranda v Arizona).
Then there's the whole history of the 14A and 15A (civil rights). Expansion, expansion, expansion.*
Fail, fail, fail--on the part of the blog [STRIKE]author[/STRIKE] hack.
Given that government is willing to expand rights, insisting that they only
observe the plain language of the 2A is not an unreasonable demand.
*And, don't forget the legislative history on the 14A. A senator expressly stated during debate that the 14A was intended to also extend gun rights to blacks.
