Tribes, and their differing characteristics, are the engine of human history and evolution—not abstractions like "free speech" and "liberty." Tribes are objectively real, abstractions are not. Tribes—races and subraces, really—projecting their genes into the future, or not, is what really matters. "Free speech" and "liberty" are nice things that civilized tribes may value and want, but they are of no utility or felicity to the extinct.
