I wouldn't necessarily put criticism in the same category as enmity, though it can be.
I agree, jane, that there are enemies of freedom, and of freedom of speech, but I didn't interpret the Tpot remark as referring to those modern people or groups. I don't think the Bible reference is to such groups either, but about the primitive tribalism that was still driving ideas when it was written. However, it's still relevant.
Such tribalism still exists, and I think it is related to racism, and to fear of change. It's quite hard to find properly educated people who are racist, though I daresay there are some. I hope the progress continues.
