You can have your A-bolt hunting rifle for sporting purposes, but talk about "assault weapons" and pistols for self-defense, and they are either against it, or want to regulate it to death.

One who is a racist, that believes a Hispanic women, such as herself, is more wise, than an old white man. The other helped to author the "Assault Weapons Ban" under Clinton. Both are bad news in my book.
