The main reason DHS and other US gov security agencies consider white supremacists a threat is that white supremacist terrorists have killed more Americans in recent years than any other type of terrorist (see the El Paso Walmart shooting, the Pittsburgh synagogue shooting, more)

Pittsburgh synagogue shooting was white supremacist because the terrorist targeted Jews because a Jewish org helped resettle Middle Eastern refugees.
El Paso shooting was because the terrorist targeted Latinos to defend whites from the "great replacement" of nonwhite immigration.

. @ConceptualJames doesn't understand terrorism, nor how terrorist analysts classify some attacks as white supremacist.
By fixating on personal bugaboos, he's effectively apologizing for white supremacist terrorism.
And that's the charitable interpretation. https://twitter.com/ConceptualJames/status/1303474502291140609

Downplaying white supremacist terrorism isn't just academic.
One of the first things Trump did in office is direct the Countering Violent Extremism program to focus exclusively on Islamic extremism, thereby ignoring white supremacist extremism. https://www.reuters.com/article/us-usa-trump-extremists-program-exclusiv-idUSKBN15G5VO

In 2009, a DHS report warned about white supremacist terrorism. Republicans took offense and DHS buried the report.
In the years since, the threat metastasized. We've seen some deadly consequences, and the evidence indicates a worrisome chance of more. https://www.washingtonpost.com/news/posteverything/wp/2017/08/21/i-warned-of-right-wing-violence-in-2009-it-caused-an-uproar-i-was-right/

Claiming that terrorism and NatSec analysts identify some terrorism as white supremacist because of critical race theory is absurd--a confidently-stated display of ignorance about how this stuff works.
And downplaying white supremacist terrorism has deadly consequences.
