Timothy McVeigh has a sequel.

The IRS has long been a Target of Antigovernment Extremists
McVeigh believed bombing the Mariah Federal Building in Oklahoma, City would have a domino effect and begin a White Nationalist insurrection across the US and Canada.

There were several failed “copycat” bombings. The building destroyed by Joseph Stack was actually a target of a bomber that acted shortly after Timothy McVeigh's terrorist attack.

Terrorists are not just from the Middle East, they can live next door.

The anti-tax terrorist that rammed his plane into the IRS office Austin, TX is going to be a Teabagger & White Nationalist hero. 'Stormfront.org the Discussion board for pro-White activists and anyone else interested in White survival." is now churning in hero worship of Joseph Stack the IRS bomber.

This is alleged to be part of Josephs Stack's 6 page rant:

"I can only hope that the numbers quickly get too big to be white washed and ignored that the American zombies wake up and revolt; it will take nothing less. I would only hope that by striking a nerve that stimulates the inevitable double standard, knee-jerk government reaction that results in more stupid draconian restrictions people wake up and begin to see the pompous political thugs and their mindless minions for what they are. Sadly, though I spent my entire life trying to believe it wasn’t so, but violence not only is the answer, it is the only answer. The cruel joke is that the really big chunks of **** at the top have known this all along and have been laughing, at and using this awareness against, fools like me all along."

The last extremist bomber we had in Chester County was David Wayne Hull:
"But, the whole idea behind terrorism is to terrorize. ... It’s psychological. It isn’t necessarily always the body count. It’s what you’re doing to them psychologically, Bullets, bombs, bloodshed and the Bible. That’s the only way we’re gonna to win this,’ he preached before the ceremony. Anybody who goes down to their death fighting for this great cause, it’s a one-way trip to heaven.’ Hull was recorded as saying. Hull, 41, of Washington County, was found guilty of seven of 10 charges after a trial in May. The case was prosecuted by Assistant U.S. Attorney Margaret Picking. Hull was defended by W. Penn Hackney.”

The IRS is a traditional target of the Radical Right. So far Stack appears to be a "lone wolf", but the investigation has just begun.

“This attack comes amid the absolutely explosive growth of the right-wing militias and the larger antigovernment ‘Patriot’ movement, which includes thousands of so-called tax protesters who believe the federal income tax is illegal” said Mark Potok, director of the SPLC’s Intelligence Project. “There is a populist rage out there about what is seen as the coddling of rapacious elites, like the mortgage bankers who kept receiving multimillion dollar bonuses, even as working Americans seem to keep losing more and more.”
