For me, the example of a physicist who dislikes gay people is particularly worrying, because it involves setting very arbitrary lines in the sand of what is acceptable and what is not. What if it was a biologist that dislikes gay people? Or a doctor? Or, say, the person in control of the CDC, as happened today? Those lines, moved once, are as good as gone. What if Trump was the same Muslim-hating, gay-hating person he is, but also a brilliant physicist? Would he than be OK in Sam's book?
