The first amendment has no effect on CA, unless there's some magical textual transformation, because it quite specifically, explicitly applies to congress
an entity that the State of California does not possess.
Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances.

If you believe that the 14th amendment was legitimately adopted, and that the federal courts have interpreted it (the 14th) accurately, then what you are saying is not the current “law.”
Federal courts have ruled that states can not deny to any person within its jurisdiction “the equal protection of the laws”. Thus, not only can Congress not infringe on the 1st amendment, state government can't either.
