"I feel uncomfortable about hate speech legislation restricting what opinions are legally allowed to be expressed" ≠ "This is all fine 👍"
There are many things I disagree with, find repulsive, find abhorrent, think nobody should do, think are wrong, etc., which I nevertheless do not think should be illegal.
As I repeatedly said, if the argument is that displaying these things in a pub is, in effect, discriminating in provision of goods and services (perhaps by making black people feel unwelcome or unsafe), or that it constitutes a breach of the peace, or some other infraction, then that's a different matter, and should be dealt with under those frameworks, but I would be unhappy about having a system where people are just not permitted to have or express certain views, even those views I disagree with (within the usual limits about things like incitement, or libel, or other standard free-speech restrictions that exist in most liberal democracies).
Do you really struggle with the concept that somebody can want to live in a liberal, pluralistic democracy with freedom of speech, where others are legally permitted to have opinions they disagree with and consider wrong, disgusting or abhorrent? Is it that hard for you to understand that being against state-sponsored regulation of opinion and state-imposed punishment for "incorrect" views is an entirely different thing from agreeing with whatever opinion is under discussion?
It's hollow to defend free speech only when you agree with the speaker.
