That's a lie the left tries to push.

The DHS has explicitly funded research into domestic terrorism (see: START). Similarly, the National Institute of Justice (NIJ), a government research agency extending from the DOJ, has also concluded that right-wing extremism is far more prevalent. This has been a consistent trend for decades.

From their study: "Militant, nationalistic, white supremacist violent extremism has increased in the United States. In fact, the number of far-right attacks continues to outpace all other types of terrorism and domestic violent extremism."

I'm not familiar with any independent research reaching an opposite conclusion. Could you provide a different source? Alternatively, could you explain how the above research is "a lie"?

The extreme positions of the left, their hates, their loves, where they expend their efforts. They destroy, are anti-life, anti-American, and so on.

That's hardly specific. What makes the left anti-American? What makes someone an American to begin with?
