They also hate their own species. This can be suggested by the fact that many liberal paleo-enthusiasts worship and anthropomorphise Neanderthals, who are a completely different species but they treat members of their own species like garbage only becauss of political disagreement. Basically they care more about a different species that died out thousands of years ago than their own species.
Those liberals also forget that Neanderthals went to war with their ancestors and where a hostile species (evident by their muscular bodies, anti-social brains and extreme masculinity) and yet they worship them as if they where Jesus Christ. First they worship illegal immigrants, then Neanderthals, whats next aliens?
