This is Gibson's statement the day after the event:
I...and said things that I do not believe to be true and which are despicable. I am deeply ashamed
I don't think you'd catch a Pharisee saying that.
The ones who are deserving of condemnation are those who continually act dishonorably...the Bill Mahrer type for example...who exhibit hateful attitudes toward people groups and go on for years about it. Gibson is different.
If he is caught engaging in the anti-Jewish rhetoric longer term I will change my opinion and say that he is truly a hateful guy. But because he expressed unqualified repentance for what he called "despicable" actions, I do not see him as a Pharisee-type.
Until he denounces his anti-semitic attitudes by name, and calls his own anti-semitism despicable, Jews will be left to wonder if he doesn't secretly still hold them.
