Keep seeing the word ‘libtard’ on Facebook. It’s a derivative of ‘retard’ used to demean those with learning disabilities & make them feel small & subhuman. Please reconsider its use out of respect. Rather, start to think of it as hate language, whether you mean it as such or not. ‘Retardation’ is a social stigma, not a scientific category of intelligence, & part of the junk science of IQ. It is used to isolate, marginalize, make vulnerable, & victimize human beings who are often wiser than the geniuses among us.
