The whole point of my examination thus far has been to probe whether or not this witness would reliably and honestly disclose his partisanship to us, and I must confess, I have found him to be somewhat less than forthcoming about that. Consequently, I would suggest that I certainly am not prepared to accept his evidence on anything, and I would highly recommend that no one listening should accept his evidence on scientific issues when he hasn't been completely forthcoming about his particular bias and partisanship.
I don't believe my questioning is inappropriate, and those are my reasons.
