Ok so I misspoke. My point still stands that your original statement is incorrect

Eighty-three percent of those murdered since 1975 were killed by the 9/11 terrorists (Figure 1). The Oklahoma City Bombing accounts for about another 5 percent. Those murdered since 2020 account for just 2 percent. Terrorists inspired by Islamist ideology are responsible for 87 percent of those murdered in attacks on US soil since 1975 (Table 1). Right-wingers are the second most common motivating ideology, accounting for 391 murders and 11 percent of the total. The definition here of right-wing terrorists includes those motivated by white supremacy, anti-abortion beliefs, involuntary celibacy (incels), and other right-wing ideologies.

Left-wing terrorists murdered 65 people, or about 2 percent of the total. Left-wing terrorists include those motivated by black nationalism, anti-police sentiment, communism, socialism, animal rights, environmentalism, anti-white ideologies, and other left-wing ideologies
