Quite so, along with this clause of the 14th Amendment: "No state shall make or enforce any law which shall abridge the privileges or immunities of citizens of the United States; nor shall any state deprive any person of life, liberty, or property, without due process of law; nor deny to any person within its jurisdiction the equal protection of the laws."

I'm not alone in thinking that California's oppressive may-issue CCW laws deny citizens the equal protection of the law guaranteed by the 2nd Amendment, and would welcome Federal intervention in this specific instance.
