It always surprised me that some people in the 1980/90s seemed to regard him as misogynist. Several of his novels had strong women characters - notably "The Glory Road".
IIRC "Stranger in a Strange Land" was a reworking of the story of Jesus Christ. Its main character's liberal attitudes to sex*** were guaranteed to upset the US religious right.
