Ditto for violence graphically done.
Only saw clockwork orange once, same for straw dogs, both at first release. (giving my age away )
In both cases the director would say that they were making important points. Kubrick had, imho, the good sense to pull Clockwork Orange from release or video release.
It was, afaik only released on DVD when he died.
I seriously doubt that we need to see rape to understand the horrific nature of the crime.
