My point is that Sarek is compulsively inflexible when we first meet him, but he's not a bigot.
As for hypocrisy... my own mother was horrified when I told her I'm atheist. And she's one of the most bigoted people I know. I'm glad I didn't follow in her footsteps, because I would have turned into the kind of person my present self would have despised.
At least Sarek found redemption and reconciliation later in life.
