Oregon Gun Legislation

Saw this linked on Gun Watch.

Why is Oregon suddenly gone so nuts? Look at Senate Bill 927 specifically.
Look at these attributes that would require a gun to be banned:

(d) Has any of the following characteristics:
(A) A centerfire rifle that has the capacity to accept a detachable magazine and any of
the following:
(i) A pistol grip that protrudes conspicuously beneath the action of the weapon;
(ii) A thumbhole stock;
(iii) A folding or telescoping stock;
(iv) A grenade launcher or flare launcher;
(v) A flash suppressor; or
(vi) A forward pistol grip.
(B) A centerfire rifle that has a fixed magazine with the capacity to accept more than
10 rounds of ammunition.
(C) A centerfire rifle that has an overall length of less than 30 inches.
(D) A pistol that has the capacity to accept a detachable magazine and any of the following:
(i) A threaded barrel, capable of accepting a flash suppressor, forward handgrip or
silencer;
(ii) A second handgrip; or
(iii) A shroud that is attached to, or partially or completely encircles, the barrel that
allows a person to fire the weapon without burning the person¢s hand, except a slide that encloses the barrel.
(E) A pistol with a fixed magazine that has the capacity to accept more than 10 rounds.
(F) A shotgun that has both of the following:
(i) A folding or telescoping stock; and
(ii) A pistol grip that protrudes conspicuously beneath the action of the weapon,
thumbhole stock or vertical handgrip.
(G) A shotgun that has the ability to accept a detachable magazine.
(H) Any shotgun with a revolving cylinder.

Well, that pretty much covers many military rifle from WWI and on. The Lee-Enfield No.1 mark 3 would satisfy this list. This level of vagueness could be interpreted that way.
The list they provide of specific guns is also huge.

Why is Oregon suddenly out of control with this legislation?
