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.
What part of "no law" don't you understand?
See post 11. Beat ya.
"No law" is pretty clear as is "Congress shall", after that your argument is hazy. The Constitution is just as silent on obscenity as it is on abortion.
It's that tricky ole commerce clause that these folks have run afoul of. If California decides that violent pornography is okie dokie then I suggest they produce it and sell it in California.
