Using that list, let's look back at the last ~40 years: 1978-1995 : Unabomber - Not WS 1980-1985 : Jewish Defense League - Not WS 1995 : Oklahoma City Bombing - WS(Possibly Political and not WS but will count as linked) 1996 : Olympic Bombing - WS 2009 : Fort Hood shooting - Not WS(Radical Islam) 2012 : Wisconsin Sikh temple shooting - WS 2013 : Boston Marathon bombing - Not WS(Radical Islam) 2015 : Cartoon Drawing Contest shooting - Not WS(Radical Islam) 2015 : Charleston church shooting - WS 2015 : San Bernardino shooting - Not WS(Radical Islam) 2016 : Orlando nightclub shooting -Not WS(Radical Islam) 2017 : Congressional baseball shooting - Not WS(Political left) 2017 : Charlottesville car attack - WS 2018 : Pittsburgh synagogue shooting - WS 2019 : Escondido mosque fire and Poway synagogue shooting - WS 2019 : El Paso Walmart shooting - WS 2025 : New Orleans truck attack - Not WS

I would note; I know of at least one missing item, the attack on protesters in Denver. I also added back in the 2009 Fort Hood shooting which was linked to the page but also missing in the list.

Also possibly missing: DC Sniper attacks

However for sake of argument, I will only look at data prior to 2021:

8/16 attacks on that list are linked to White Supremacists(Counting OKC) ~50%

In the last 15 years, again about 50% are linked to White Supremacists and ~41% linked to Radical Islam.
