I know it’s stylish to use “hate” to mean anything from noticing the distinction between one statement of fact and another, mutually exclusive, one, to disapproval of an action or choice, to disagreement on matters of lifestyle preference, whereas loathing and hostility are worlds away from such issues. I don’t know why. I guess it must be a pendulum problem: Maybe the style is now to call anything short of full agreement and unlimited affection “hate” in reaction against the fairly cold attitude of past generations. Just trying too hard to avoid the mistakes of other people long ago. I think that makes some sense but it does get irritating to try to pin down what people mean who keep answering everything with “But don’t you think the time for hate is past?” when no one but them ever said anything about hating anyone. Is that what you refer to?
maybe the word “hate” should be reserved by social convention for those who can point to what they mean specifically.
