There’s nothing obvious about this. Hate is entirely in the eye of the beholder, and is no different from the idea of “offensive”. People are free to, and routinely do, read hate into all sorts of things where it’s not at all obvious whether it was intended.

You also won’t be able to prove that hate it always wrong. Is it OK to hate Nazis? Is it OK to hate people that have harmed you? Is it OK to hate people that want to harm you? Is it OK to hate people that hate you? There is no obvious place at all to draw the line on that.

Finally, all facts are disputable. There are entire disciplines devoted to disputing facts. Science, philosophy and logic all revolve are hypothesising, disputing and falsifying facts. In the centuries that humans have been pondering logic, the combined efforts of everybody who has ever lived have yet to produce a single objective truth.

Asserting that people should hold the ‘correct values’ before being entitled to express themselves is simply asserting that your own orthodoxy should be universally enforced. This idea comes directly from Orwell in the form of ‘wrongthink’.
