IRL, "vile kluxers, neo-nazis or garden variety smarmy psychopaths" keep a low profile, as much to themselves as they can choose. They get run off sites like
Conservative Cave or
The Briefing Room as readily as they would on DU (though some conservatives might briefly use them as "chewtoys", just to have fun and make clear to them how unwelcome "vile kluxers, neo-nazis or garden variety smarmy psychopaths" are - BTDTGTTS,
).
OTOH, while BLM and
Critical Race Theory racists are embraced by DU, conservative sites give them the same treatment as "vile kluxers, neo-nazis or garden variety smarmy psychopaths".
