Why is it more acceptable that some GT cars have automatic transmissions and others don’t?

Personally, I can’t fathom a Jaguar XJS, Porsche 928 or BMW 8-series with an automatic in my garage. Unfortunately the majority of those models out there are autos. But, if I were ever to get a 928 or 850/840 I’d require it to have a manual transmission. At the same time other competing GT cars like the Mercedes SEC were automatic-only and I’d love to have one of those despite the slush box. If I view these cars empirically there is a cognitive dissonance. Instead of outright rejecting the SEC because of its lack of a third pedal I accept it, while I reject XJS, 928s, and 8-series which are autos. I’m far more troubled by this than I should be.
