The fbi and homeland security come out and say white supremacy is the greatest threat when it would be way way down the list if they actually were basing it off anything real.
Obama was in power for almost a decade. The democrat party had time to change everything. The fbi was likely put through white privilege classes.
It may be to the point where you didn't get promoted to the top ranks unless you were some type of social justice warrior.
Why else would the most important things they do be investigating nooses for Nascar and the biden bus. Its from what they were taught that you have to fight against white supremacy. I belive they include stuff like microsgressions against minorities to be violence so that is why they don't feel riots and antifa are a big deal.
Politics is downstream from culture. So it makes sense that FBI policy and actions flow downstream from FBI culture.
