Most recent terrorist attack in the US was the 2019 El Paso attacks, which was a White American Male who killed 23 people
Before that another white american male in Poway (and an attack on a mosque earlier than that), another in the Pittsburgh synagogue, the Blaze Bernstein shooting, and if you don't include the ones where nobody died - the mail bombing attempts aimed at people like Obama and Biden
One thing all these terrorist attacks on american soil have in common? The perpetrator was a white american male.
This doesn't mean that all white american males are terrorists, but if we were to take the attitude that many have towards Muslims, white american males are at best supporters of terrorism.
