Mauricio Garcia — not Caucasian — shot up a mall north of Dallas, and the corporate media immediately seized on the shooting immediately to advance the narrative that it was a White Supremacist™ hate crime.
As others have pointed out, months later there is still no official ideological explanation for the transgender shooter in Tennessee who wrote a manifesto, presumably filled with LGBTQ+++™ propaganda, and then shot up a school in service to it.
The manifesto has yet to be released for public scrutiny. Of course, we all know that if it contained white supremacist content as opposed to LGBTQ+++™ dogma, law enforcement would have leaked it to the press without delay — probably on the same day as the attack.
In contrast to the hide-the-ball game with the transgender manifesto, within mere hours of the Dallas shooting, before the bodies were cold, the narrative had already been cemented that White Supremacy™ was the ideological culprit.
