Generally the reaction is not to minorities(non-white, is what I am assuming you mean) but to people from outside of a group trying to tell a group what words to use i.e. LatinX.
An aside: If someone who is white is talking to the Spanish speaking community, would they be considered a minority? If so, then the parent premise would hold true.
