> Excluding people based on their beliefs is completely a judgement call about whether you think their beliefs are so far from your own that nothing productive can come from sharing a department with them.

Would the author of this comment be willing to say the same thing if the shoe were on the other foot? 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's very possible for the school to say "nothing productive can come from sharing a department with them".
