That’s a kind of philosophical one. I my opinion (note my personal opinion) it is possible to classify races and ethnic groups in human and subhuman as we have certain criteria which separates a human from an animal. This is the same foundation which legitimates prison sentences for criminals. Every human has the ability to feel compassion and pain and has the ability to act rational by suppressing drives/desires of a long period of time to archive higher/complex goals. Animals, on the other hand, act through genetically predefined instincts to satisfy short-term urges/desires.
History has shown that some racial and ethnic groups are more likely to belong to one side than the other. The USA especially Florida had their own rapefugee moment when they got invaded by Cubans (most of the former criminals) back in the 1980 ().
Your opinion is nothing but baseless racist bullshit. We are all human.
The only sub humans being discussed here are the shape shifting lizards, and Roms is onto them.
