&#x27;Say, a high school refusing to hire someone based on their liberal beliefs (say, transgender people being able to use the bathroom they identify as)? After all, it&#x27;s very possible for the school to say &quot;nothing productive can come from sharing a department with them&quot;.&#x27;<p>Yes, the school could say that, but they might not be right (a case of a valid but unsound argument). In any case I view that hypothetical (barring a teacher based on what they think about transgender bathroom priveleges) as preferable to, say, barring a teacher based on something they had no say on such as their skin color (although, as I must continue to point out-- that doesn&#x27;t mean it&#x27;s not also preferable to not discriminate at all!)
