Left-wing extremists do exist and commit violence, but unlike those on the right, they typically target property rather than people. Right-wing extremism is the most dangerous movement facing the US due to how broad it is. From individual hate crimes to mass shootings targeting people of color and the LGTBQ+ community, the white, straight, and male supremacy ideologies have garnered tremendous support, leading to this dangerously high spike in violence and death.
The so-called studies published by the ADL in recent years have fraudulently rearranged real statistics to promote blatant lies and brainwash the American people into thinking conservatives are the evilest among us. It does this by secretly combining groups such as Islamic radicals with white supremacists — who don't embody conservative values — while conveniently ignoring the vast majority of shooting deaths committed by non-ideological gangs. The US does face a lot of violence, but it has little to do with either left-wing or right-wing extremism.
