That's damage control, he can't afford to be blacklisted by hollywood. Any guy who get's metoo'd and wants to "keep" a career, better have their head down.

Secondly, to say his past confirms an attempted rape, is totally stunned. There is more evidence that she made up the whole thing, you don't think her story was "off", not to mention her past and the way the story was presented? C'mon, it's obvious.
Third, If Kavanaugh had of said what you suggest, he would not have been confirmed. It's rather naive of you to believe that he would've been forgiven.
