Stormfront has been around for decades, getting little traction. It's partly David Duke's site, or was. Now it's just a forum. It's about as nutty as the usual white militia crowd, with which there's some overlap. Compare "vdare.com", which is somewhat white supremacist and pro-Trump. There's a whole spectrum of groups like that.
This was a bad decision by Network Solutions. If registrars start censoring everybody the ADL and the Southern Poverty Law Center don't like, they're going to run head-on into the Trump supporters. That won't end well.
