I don't think she is invalidating anything there. It seems that there is a gap of difference between those Cubans who live in Miami and those who are living in Cuba. As a Puerto Rican and a Latina, I can understand both sides of this situation. Sometimes people can run hot over political issues (Puerto Ricans, too, considering what is going on with us in terms of status and finding identity). Each one is expressing their perspective, but I don't think throwing water into a pan of burning oil is going to solve it, PanAfrica. It seems like a conversation that must see its course. MooMoo is trying to say that it is different in Cuba and that Etero is not really aware of the situation for Black people there. Please don't incite a situation here! There is no where I read where it says "Go to hell with that!" You are interpreting it in too literal of a way and are missing its tone and Latino perspective. Etero is speaking of his experience in Miami with the Cubans (who are mostly white and are the ones who fled Cuba). MooMoo is explainging that those types of Cubans are like the elites who still hold on to racist perspectives.
Please be cordial. As passionate as each one sounds, this is just how Latin people talk sometimes (doesn't make everything correct). Still show some love when talking and discussing.
