(CNSNews.com) - The National Rifle Association opposes additional gun regulation as the "slippery slope" that will lead to more and more gun restrictions on law-abiding gun owners, while doing little or nothing to prevent the criminal misuse of guns.

And recent events -- Democrats demanding gun "buybacks" and other gun ownership encroachments -- have proven the NRA right, say conservatives who support the Second Amendment.

"Well, I think that this vindicates kind of what the NRA has been warning from the outset," conservative author, filmmaker and pundit Dinesh D'Sousa told Fox News's Laura Ingraham Tuesday night:

At first, for many years, I thought that the NRA was kind of using, you may call it the 'slippery slope' argument, which was essentially that once you start outlawing one type of weapon, you will then slowly proceed to outlawing the next type and eventually it becomes a kind of a comprehensive confiscation. But I think what's interesting here is this isn't even a slippery slope. It now appears like there's a whole group of people that from the outset want a comprehensive ban, and these mass shootings are making them come out of the closet, you may say rhetorically, and be more and more frank and candid about what their real agenda is. It never was a kind of targeted or narrowly tailored law. It's ultimately an all-out assault on the Second Amendment. And let's remember, too, Laura, that the Second Amendment is no less important than the First Amendment or the Fourth Amendment, so we should very jealously guard against these constitutional rights being stripped away based upon some sort of pretext. If you're going to abuse your rights, the solution is not to take away my rights.

D'Souza was talking about Democrat presidential hopeful Beto O'Rourke who, this past weekend, admitted he wants the government to confiscate semi-automatic weapons from everyone, including the vast majority of people who do not misuse them:

“So I want to be really clear that that’s exactly what we’re going to do,” O’Rourke said on Saturday at a campaign stop in Virginia. “Americans who own AR-15s and AK-47s will have to sell them to the government.”

On Tuesday, after Walmart announced it would stop selling certain types of ammunition and ban open carry in its stores, O'Rourke called it a "step in the right direction."

"I'm grateful Walmart has taken action," O'Rourke tweeted, "but we can't rely on corporations to stop gun violence. We need universal background checks, we need red flag laws, and we need to buy back every single assault weapon."

Sen. Elizabeth Warren says that she, as president, would also try to pass a federal assault weapons ban. "We should establish a buyback program to allow those who wish to do so to return their weapon for safe disposal, and individuals who fail to register or return their assault weapon should face penalties."

D'Souza noted that the U.S. Supreme Court, in the Heller decision, said that the individual right to own a gun may be regulated. "But there's a heavy burden of proof for those who would want to infringe the constitutional right," he said.

D'Souza also pointed to Venezuela where the late dictator Hugo Chavez confiscated citizens' guns: "The moment that the citizens were deprived of their guns, he unleashed criminals and so-called collectivos and had state-licensed thugs on the streets to be able to move into your apartment, take your stuff. Why? Because he had disarmed the citizens in preparation for that."

D'Souza said mass shooting, which bring calls to do-something, are "anomalous," while there are shootings every day in every major city.

"It's very odd that those don't lead to demands for gun control. In fact those don't lead to demands for anything. It seems that only when there is a mass shooting, an anomalous event, suddenly people go, let's confiscate the guns of everybody in America because everybody with an assault rifle poses a threat.

“No, everyone with an assault rifle does not pose a threat. These guys pose a threat -- let's identify the threats, find out how we can preempt it and deal with it in a tailored and narrowly focused way," D’Souza said.
