The humour is only misogynist if he is being serious, which clearly he isn't.
As to bad taste that's subjective (just like his opinions).
As I said earlier there is a difference between Warren Mitchell playing a bigot and Warren Mitchell being a bigot.
Certain types of things are misogynistic even when they're meant as humor. The humor here is clearly misogynistic. Clearly he is not being serious about keeping women tied up in his basement, but putting it forward as a joke is misogynistic. And humor is often used as cover for bigotry, such as in various comedians' routines -fake bigotry that really is real bigotry.
