Tucker Carlson starts out by saying he respects Eric Guster. Calls him a reasonable, smart lawyer. He points out that the left dislikes Trump so much that they are unable to clearly hear what he says and their judgement is affected. Take a look at the exchange between Tucker Carlson and Liberal attorney Eric Guster.
Tucker Carlson vs Eric Guster
Guster found that there was race hatred in the speech. When asked where the racial hatred was in the speech, he was unable to point any out. What he did was talk about how Trump has created a racial divide between Mexicans and Muslims and Americans. Then from there he made the comparisons to Hitler. Also because there were Confederate flags in an Alabama rally, this also is directly related to Trump being racist and similar to Hitler.
