What is Wrong with White Christian Men?

What do serial killers Ted Bundy, Jeffrey Dahmer, John Wayne Gacy, Earle Nelson, Henry Lee Lucas, Gary Ridgway, Dean Corll and Wayne Williams have in common? They are white Anglosaxon Christians. There are only two black serial killer: Samuel Little and John Allen (the "D.C. sniper" of 2001).

What do mass shooters Connor Betts (Dayton nightclub, Aug 2019), Patrick Crusius (El Paso Walmart, Aug 2019), DeWayne Craddock (Virginia Beach, May 2019), David Long (Thousand Oaks, Nov 2018), Robert Bowers (Pittsburgh synagogue, Oct 2018), Dimitrios Pagourtzis (Santa Fe High School, May 2018), Nikolas Cruz (Stoneman Douglas High School, Feb 2018), Devin Kelley (Sutherland Springs church, Nov 2017), Stephen Paddock (Las Vegas, Oct 2017), Adam Lanza (Sandy Hook, Dec 2012), James Holmes (Aurora theater, July 2012), Eric Harris and Dylan Klebold (Columbine High School, April 1999), George Hennard (Killeen, 1991), James Huberty (San Ysidro, 1984), Charles Whitman (Austin, 1966) and Patrick Sherill (Edmond, 1986) have in common? They are white Christian men. There is only one (one) mass shooting carried out by an Asian, Seung-Hui Cho (Virginia Tech, Apr 2007), and two (two) carried out by Muslims: Omar Mateen (Orlando nightclub, June 2016) and Syed Rizwan Farook and Tashfeen Malik (San Bernardino, Dec 2015). Not a single mass shooting by a black man (more than 9 people killed).

Mass shooters and serial killers are white Christian men, with rare exceptions, and frequently with Anglosaxon last names.
("Mass shooting" and "serial killer" here refers to more than 9 homicides. The higher the threshold you choose, the more likely that they are mostly white Christians with an Anglosaxon last name. The lower the threshold, the more likely that there are also other groups. Racists lower the threshold of "mass shooting" to two victims so that most killers are from poor violent neighborhoods, i.e. blacks; but most of us think that a "mass" shooting is not a shooting of two people; two is not a "mass".

These are routinely classified as cases of "mental illness" but why is it that this kind of mental illness seems to affect mainly white Christian men born in the USA? Note that articles on these mass shootings often omit the name of the shooter (they normally only mention the place and date), whereas any article on an Islamic terrorist attack would include the names of the attackers (to emphasize their religion and origin).
