There is no suppression of science regarding race. "Human Bio Diversity" shills try to push a political ideology and scientific semantics is their trojan horse.
Noone denies that human subgroups exist (but clusters of ethnicity is the real subunit rather than major 'races' like 'black'). You have plentiful research on ethnicity-specific genes for disease, and in the fields of ethnography, anthropology. Ethnic science is blooming.
The problem is that genetic diversity among humans isn't enough for you. It's just a means to an end for advocating ethno-fascism. Humans having different inherent abilities, being slightly stronger or dumber than each other, does not imply that discrimination and segregation is necessary. Similarly, two brothers having an IQ difference of 0.2 doesn't mean that ""meritocratically"" one should be king and the other a shit shoveling slave.
Now, 'destroying subspecies' like white rhinos due to inbreeding is genocide by definition if it was forced, because a forced destruction of a culture or peoples is genocide. But as much as you postulate it's not forced. Most white voters are pretty happy with migration of all colour, and in practice people date mostly within their own ethnicity, probably due to cultural similarity and community ties. Even if they chose to racemix, they're doing it out of their own accord, so it's not genocide.
Even in this meme you are not content with making an appeal that human bioscience is cruelly suppressed without insinuating that ethnonationalism is necessary and that Jews control the world.
