Intertwined with anti-black racism in the Latino community is anti-black racism in ALL immigrant communities in the United States. It sometimes seems as though racism is handed out along with a visa. I used to represent a large number of African immigrants, primarily from Liberia and Sierra Leone. They uniformly bore incredibly strong animus toward African-Americans; indeed, they used the term "African-American" as an epithet, spitting out the syllables The head of a Liberian community association told me that he hoped his daughter would marry another first-generation African immigrant, but if not, he wanted her to marry a white guy or anyone but an "African-American." (Yes, the irony. Their kids, born in the US, were the epitome of "African-American," but they eschewed that label in favor of national ("Liberian") or tribal ("Kpelle") self-identity. The fact that Liberia was founded by "African-Americans" didn't deter the Liberians, either).
Whenever their children got in trouble, they blamed it on any African-American friends the kids happened to have.
This same visceral, old-school racism was also on flagrant display in the Russian, Korean, Chinese, Azerbaijani, and Iranian immigrant communities I worked with -- but the African immigrants were the worst, because they felt that their skin color gave them cover to be much more openly and overtly racist toward African-Americans.
Racism in the Latino community seems to me to just be part-and-parcel of the racism I encountered in all immigrant communities.
