Leftists and Democrats don't like facts when it comes to the sad states of their cities. So they have to deflect. The whole of the pseudo-cultural identities rest upon the dysfunction of their cities and their favored Democratic Party politicians.
Those who are claiming that Trump criticizing Baltimore and Elijah Cummings is racist, they are the true racists when it comes down to analyzing things. They're the ones applying, with their own mind, the thought that so-called 'diversity' has led to Baltimore's problems. Trump certainly didn't say that. Democrats are, in a figurative sense.
