Map of Hate Groups in US
http://www.splcenter.org/get-informed/hate-mapI guess I was living in oblivion when I lived though out California. They lead the country with the most hate groups, disgusting.

California has 38 million people. That's 12% of the US population. For comparison? Georgia has around 10 million people. Mississippi? Around 3 million. Relative to population the majority are where you'd expect. (And it's also useful to note that they include black separatist groups like the Nation of Islam and radical groups like the Jewish Defense League, and not just KKK/skinhead/white nationalist "hate groups"
.
Seriously, search some threads about the Zimmerman trial, it's rather grotesque. You will often see DU'ers exploring every possible option to explain a racist incident except for racism - unless of course the victim is white, then we get smug "told ya so's!" The new one is the claim that the Michael Dunn trial jury was too progressive to convict him on Murder 1 because they didn't like the death penalty - it couldn't be because someone on the jury simply didn't think it was worth a murder charge...
Also a lot of hate delivered towards muslims. Islamophobia for DAYS on DU. Plus just general hatred and bloodlust towards the non-Israel middle east as a whole; We have people who think that a bloody military Junta in Egypt, massacring civilians, treating Journalism as terrorism, is a great thing, becuase the alternative might be a democratically-elected government passing a law against alcohol sales or something. To say nothing of the bloodthirsty ranting of people who wanted to massacre Syrians in airstrikes so that we could "send a message" to iran - or just as often simply because the president thought it would be a good move.
While lurking on DU I saw people defending antiziganism (hatred at Roma and other traveler / gypsy groups) by claiming - of course - that those people are all thieves and kidnappers. it was recently reprised on DU3 when there was a story about a Roma couple who apparently DID kidnap a child, their crime was thrown onto the entire ethnic group by DU.
And of course there's the transphobia - I never thought I would see a trans woman referred to as "it" on a place like DU, but that was a frequent expression with regard to chelsea Manning, as wll as the usual "He was born a man i'm going ot keep calling him a man!" shit.
I could make mention of the biases against women here, but there are other posters who could give you what's probably a clearer account.
Basically DU is only fully welcoming to white cis-males. others are "tolerated" or treated like fashion accessories. 
I know I'm not the only white cis-male who's bothered by this of course, it's not exactly a club we have... but it's the way any unmoderated place on the internet will go - along with the brainless right-wingerism that seems to have taken root here in general. A lot of worm-eaten driftwood has piled up on the shores of DU.
but, yes, there are a lot of guns here. A lot of people hunt, and a lot of people have them for protection in the wild ... and some people are just macho assholes, like everywhere else. 
They have a least one "Get Off My Lawn" chapter in every state.
