Personally, I prefer my political philosophy and analysis to come from people who haven't imagined a bizarre alternate reality in order to correlate their theories.

Once you decide humans you don't trust/disagree with/feel threatened or persecuted by are in fact not human, but are demons/lizards/aliens, then you don't have to treat them as humans anymore. Dehumanizing real people, regardless of whether they are powerful or wealthy or evil, is wrong, no matter how appealing. Such beliefs cloud judgement and enable atrocity.
