Comparing history of right and left political violence:
For decades now, the most serious threat of domestic terrorism has come from the growing ranks of paranoid, anti-government hate groups that draw their inspiration, vocabulary and anger from the far right. It is disingenuous for mainstream purveyors of incendiary far-right rhetoric to dismiss groups such as the Hutaree by saying that there are “crazies on both sides.” This simply is not true. There was a time when the far left was a spawning ground for political violence.
The article catalogs Patty Hearts, etc. and other acts from the left in the 1970s.
By contrast, there has been explosive growth among far-right, militia-type groups that identify themselves as white supremacists, “constitutionalists,” tax protesters and religious soldiers determined to kill people to uphold “Christian” values. Most of the groups that posed a real danger, as the Hutaree allegedly did, have been infiltrated and dismantled by authorities before they could do any damage.
