It's an interesting question. For me personally, there will always be some level of taint. But we all also have our own tolerances
So something like net-value = value - (taintedness - tolerance) and the higher the net value, the more likely I'll buy
Like, Sagrada Familia to me has an incredible value because of how crazy the architecture is and how crazy it would be as a lego build. Still has a decent amount of taintedness cause catholic and my tolerance for catholic stuff is low.
But U.S. Air Force Academy Chapel in CO is a dope looking building so a high value. It does have catholic chapels but also has many different other chapels, which I think overall reduces the taintedness over a straight up catholic churches.
