Clearly you don't have the full picture. This isn't about a difference of views; it's about a long-standing pattern of inappropriate behavior, including (but not limited to) overtly and deliberately staring at women's breasts in a professional context. There's no innocuous explanation here; this isn't an isolated mistake.
Many people (and Richard too[1]) have wondered if he is somewhat on the autistic spectrum. An "innocuous" partial disability would cause poor social interactions, and would lead to difficultly learning social nuances.
Of course he could also just be socially inept (i.e. no excuse for failing to learn good behaviour) and he clearly isn't disabled (anyone actually dealing with autism is doing life in hard mode).
Let's assume he's on the spectrum for the sake of argument. If you miss some indirect signals, that's one thing - but when you're explicitly told specific behaviors are inappropriate, and you keep doing them anyway, being on the spectrum is not a defense.
