Two good resources when you hear that right-wingers are responsible for more acts of terrorism
VERY FAKE NEWS
First, use a meme to mock them: https://kekpe.pe/i/5f5a36163b6ae.jpeg
Then, use this article to break down the flaws with how the report was put together: https://www.americanthinker.com/articles/2020/07/how_the_left_creates_fake_studies_to_fabricate_rightwing_terrorism.html
I used that exact article on this exact topic.
The guy went: "Deerrrr, American Thinker is far right propaganda, deerrrr"
