A Clinton appointee, Federal Judge Catherine C. Blake made one of the most ignorant rulings I have seen on Guns.
To call AR and AK platform rifles dangerous and unusual arms and not covered by the Second Amendment is a ruling that will be overturned on appeal.

Incorrect.
The ruling is consistent with other rulings concerning similar restrictions in Connecticut and New York, and is consistent with current Second Amendment jurisprudence. holding that although jurisdictions may enact bans on particular types of firearms, they may not ban firearms outright. Such restrictions are Constitutional provided citizens have some type of access to firearms for self defense.
From your cited article:
The Act substantially serves the governments interest in protecting public safety, and it does so without significantly burdening what the Supreme Court has now explained is the core Second Amendment right of law-abiding, responsible citizens to use arms in defense of hearth and home,  she wrote.
A 'significant burden' would manifest should a jurisdiction seek to prohibit possession of all handguns, or firearms overall. Laws allowing the possession of handguns, rifles, shotguns, but not AR or AK platforms are Constitutional because they do not violate the right to possess a firearm pursuant to lawful self-defense.
Consequently it is the OP who is ignorant of the law, not the judge who is 'ignorant' of firearms.
And that Clinton appointed the judge who ruled in this case is irrelevant, as the judge who ruled that the New York SAFE Act banning AR platform rifles was Constitutional, Chief U.S. District Judge William M. Skretny, was appointed by George H.W. Bush in 1990.
Thus the OP's effort to contrive this into some sort of 'partisan issue' fails.
I acknowledge and accept the fact that this is indeed current Second Amendment jurisprudence, although I disagree with it. This and similar rulings are likely subject to appeal, and may eventually come before the Supreme Court, at which time a determination will be made that the Second Amendment right is more comprehensive, placing a greater burden upon the state to justify the banning of specific firearms, invalidating New York's SAFE Act and like measures such as the one in Maryland.
