I feel no need to go around publicly denouncing my own father when he says things I disagree with. Really, now, there is a difference between making a mistake and spewing venom. The former can be overlooked out of courtesy; the latter has (in Gibson's case) reached the point where the only available options are 1)objection or 2)tacit concurrence.
So according to steve-b, Mel Gibson only has two "available options" - publicly denouncing his 85-year-old father, or accepting that steve-b thinks he's a Holocaust denier.
My guess is that Mel Gibson doesn't really care what steve-b thinks, but I guess we'll have to stay tuned.
Know what? I disagree with a lot of what my own folks have to say about this and that. They come from a different time and place. I expect that holds true of almost everyone, including Mel Gibson.
I don't see how it's any business of yours what he does about his, what I do about mine, or that you have any standing to demand that he do anything about his family, anyway. In a world of Hollywood, his family looks exceptionally wholesome.
I hope Mel cleans up, big time.
