The latest poll, of registered voters: https://www.politico.com/f/?id=00000163-8a22-d9c0-a1f3-feb320370001 See pages around 122 and down. Highlight: About (over) 90% of the polled, and about (over) 90% of the gun owners among the polled, support background checks on all gun sales strongly or somewhat. About 90% of Republican voters likewise. That is about twenty points higher than the already strong majority percentage (67 shade 2) who favor stronger gun control laws of any kind, demonstrating once again that a large fraction of Americans either does not realize that universal background checks are not already required, or does not think of them as "gun control" legislation.
So they're subcultures that do not appreciably differ from their parent cultures? No assumption involved. California clearly believes its law enforcement can use weapons civilians can't. Tell it to Californians. No, I live in a free state. Read it again. I didn't mention all of them. Look at how many respondents actually know what they're talking about. Look at history to see how public opinion polls rarely translate to political will for specific policies.
Not "parent" cultures - companion, maybe. Yep. They are American mainstream, part of the one encompassing culture, according to your link criteria. Your bogus assumption had nothing to do with California - and you know it. [That's harder to extricate from than slip into - like a culture of bribery, everything adjusts to fit.] That won't stop them. You can't say you weren't warned. The large majority of Americans, including most Republicans and more than 80% of NRA members, favor universal background checks. This is a fact. To deny it you not only have to dismiss dozens of polls taken over the past thirty years, but assume the best and most thorough of these polls are wrong by twenty or thirty points. It's so much favored that many people - even NRA members - think it already is law. That's common enough to be a recognized obstacle in breaking the bothsides jamb - the gun nut side tends to be especially deluded in that regard.
I am fully aware you cherry picked. So: Ice: Pretty much everybody wants universal background checks. Vociferous: again, this is a false claim BVN: Here is proof that it is true Vociferous: Well, OK, so what if everyone wants universal background checks? Doesn't mean a law will be passed. Awaiting the next backpedal.
