How about simply starting with Øfeuhrer's mentors. Try googling about the bombings and deaths that the group led by Bernadette Dorn and Ayers.
Actually, absolute FIRST on your list should be the Five police officers in Dallas that were assassinated by long range rifle fire from a fine upstanding BLM terrorist.
Add in the hundred some odd men, women, and children that were killed in Waco at the behest and command of one LEFT WING FEMALE ATTOURNEY GENERAL.
How many trannies have you met that are NOT hard-core lefties ? BY all means add in a multitude of child murders by those loons.
Or how about the Las Vegas shooter - whose investigation was so conveniently stopped by a LEFT WING ADMINISTRATION ? What was that, another 86 or so human beings ?
Add in how many from 7 October, 2023 from left wing terrorists fully supported by a left wing US administration, and fully supported since by HOW MANY left wing universities and agitators.
How many people were killed by left wing 'mostly peaceful' terrorists during the 'summer of love'.
How many people killed in Seattle during the 'chaz insurrection'.
Oh, if ya really wanna piss of your left wing contacts, point out to them that the ONLY TWO DEATHS on the jan6, insurrection were at the hands of two Very left wing police - BOTH BLACK, one male and one female. The female beat a woman to death who was lying on the ground - and the CORONER AND LEFT WING DOJ completely covered up that murder.
That should give ya a decent leg up to the start of actually productive research.
