Yes, those with ideas you "abhor" shouldn't be hired. In what way do you find this materially different from shunning blasphemers?

Well you notice that I put the two different things side by side in the same sentence to make it really really easy for you. Let's do it again with "theocracy" and "shunning blasphemers." You're shifting.

Here's a hint: at no point have I said that faculty who come out with horrible views should be fired. I also haven't said that people with horrible views should be fined, imprisoned, or banned from publishing. I just don't think they should have an easy time finding a major publisher to air their horrible views or a major newspaper willing to run a holocaust-denying opinion column, a state of affairs which it is left to the owners and editors of such outlets to induce - not the state.

I think being nasty and stupid should cost you. I think we should minimize the nastiness and stupidity and time wasted by such people.
