The legal definition of hate speech (or rather, its local equivalents) is not just "any ideas counter to beliefs I hold dearly".
The US government is quite literally shooting dead American citizens in the street with zero consequences. You have a president who was found in civil court to be a rapist. He was impeached and had dozens of charges brought against him. He's unilaterally murdering people at sea and kidnapping foreign leaders.
EU countries balancing the right to freedom of speech against other rights is a drop in ocean compared to what's going on in the land of the free.
America wants to be free to spread fascist propaganda and child sexual abuse material all over the world, i.e., it's utterly degenerate culture.
You are free to try, we are free to ban it. It's all good.
at this point it's the #1 principle of the UK government, everything else comes second after putting people in jail for saying the wrong things
Like the linked article states: the law doesn't permit the police to do what they do. Even if you implement an America-style "you can even yell bomb in an airport" speech law, the cops would still arrest people to intimidate them. Changing the law does nothing when the police force is simply ignoring the law.
that's not even remotely close to reality, you have zero understanding of what the free speech laws in america are if you believe this is covered by the first amendment
