Are the sexual and racial politics sketchy of the man behind Fritz the Cat and that notorious Mr. Natural strip involving a headless woman dodgy as hell? No question about it. But, for 50 years, any cartoonist dealing with autobiography, the intricacies of their id or satire of almost any kind has HAD to contend with Crumb's extraordinary, ground-breaking work. Hell, other cartoonists even ape the guys affectations (78s obsessiveness, thrift store suits). To ignore him completely is only to invite accidentally ripping him off; he's the Bob Dylan of the comics underground, and his work is embedded in the medium's DNA now.
