Clickbait nonsense. This whole article is written about another article from some supposedly popular website I've never heard of. While the article claims it's one of the most visited sites in the country, a bit of research shows that it gets 96,000 unique visitors every day. Not so impressive compared to even minor conservative sites like the Daily Caller and Ricochet, which get about half a million and 23,000, respectively. Hell, if this is "one of the most read websites in the country" then cracked.com must be the new paper of record, with almost 1.5 million visitors each day.
The actual article, which your link doesn't link to, is also not criticizing the New Black Panthers for *having* guns, but rather for using guns to intimidate people by marching around presenting themselves as paramilitaries. A rather different scenario than your article presents things as.

Provide a legit source for people opposing the New Black Panthers following existing gun laws and we can talk. Almost unanimously, I expect pro-Second Amendment types to have no problems with any individual exercsing their right to keep and bear arms. The issue here, is one even exists, is concern about how the New Black Panther Party (which is a front for the Nation of Islam UFO cult, not a continuation of the original group) may be using the weapons to stir unrest. Call me crazy, but that strikes me as a legitimate concern.
