I don’t know if I’d say comics has a lesser proportion of total shitbags - creators in that medium might just as a whole be less visible than folks in cinema? Comics has vocal misogynists like Dave Sim, Bill Willingham, Scott Adams, and J. Scott Campbell, Objectivists like Steve Ditko, racist hawkish conservatives like Frank Miller, and sex pests like Warren Ellis. Some of the most widely distributed comics ever are the tracts of Jack Chick, theocratic fascist, racist, misogynist, homophobe.
I know the OP notes in a caveat that “[t]here are a few controversial creators in the medium,” but I don’t know if it’s so small a number as to just be brushed off in a caveat.
