Both things are true.

Hispanics are set to become the largest racial demographic soon. ~13% of the population is black.

Houston is one of the, if not the depending on the report, racially diverse cities in the country. It's a bit self segregated geographically, but is pretty impressive and there is a lot of culture to be found. Large Asian community with substantial communities from countries that don't really exist elsewhere in the state.

The state is also more or less purple outside the voting booth. Major metro areas have higher concentrations of liberals. Etc etc.

Pretty much a microcosm of the USA.
