The more accurate title would have been the inclusion of the word some. After all, a very large percentage of whites, particularly those living in the ~125 metropolitan areas of the country, are not racist or at least try to not be.
The thing common to white supremacists is their consistent low self-esteem, and, ironically, the resulting racism that actually does make them inferior. The rest of us are nothing like them. We really believe that black lives matter. I don’t recall, even as a young child, ever seeing someone of a different race or ethnicity and thinking I was better than them. I just thought they were people, like everyone else.
I have no idea who Tomi Lahren is, but as a racist she qualifies for the people-to-be-shunned category. She has nothing of value to offer any of us, except perhaps as an example of what the worst aspects of human nature can be like.
