This is a mis-truth which has been spread by Joe Rogan and his ilk. Political speech is very much protected in UK law. You won't get in "trouble" if you make posts against immigration or trans people. J.K. Rowling and Ricky Gervais certainly haven't been locked up.
Yes, there have been cases, such as the infamous Cowley Hill School case where Hertfordshire police arrested a couple over their posts in a school WhatsApp group. However, such arrests are illegal and in that case the police had to apologise and pay compensation.
What will get you in trouble in the UK is threatening violence against people or posting hate speech that encourages others to do so. But this is also true in the USA and in most countries.
With "protected political speech" being defined as which flavour of the established, incompetent elite you prefer this year.
People have been arrested in the UK for holding blank signs within vicinity of Palestine marches. People have been arrested over protesting Charles' coronation. To say nothing of thousands of people arrested every year over tweets.
Political speech is basically criminalised in the UK at this point. This is not an establishment worth any of our respect.
Got a source on this one?
Supporting Palestine in the UK has never been illegal. Supporting the specific group "Palestine Action" has been as they were for a while a proscribed terrorist organisation due to what was (IMHO) some property crimes committed against defense contractors by some of their members. Totally wrong, and has now been struck down in the courts, but saying "you can't support palestine" is also wrong.
> Thousands of people arrested every year over tweets.
The source I saw on this one had clear examples of violent threats and calls to set buildings full of people on fire, so I'm not sure this is clear either.
The line is quite thin and ambiguous though. If they want to get someone they will and find that various remarks “encourage violence”.
Almost any opinion that isn't nice can be argued to encourage violence.
Not to say anyone would actually get in trouble for just some opinion posts, but I don't know why you went with "against" here, I think "for" is the more likely one to make the current UK (or US) government upset.
Not sure how often that happens coming to the UK, yet.
Of course AFAIK this can happen pretty much everywhere at this point so your only hope is being a citizen of a country that doesn't allow it for locals (such as the US) and then not traveling. Or wipe your devices prior to traveling.

But given the increasingly dystopian state of many countries worldwide, you may also encounter difficulties related to administrative burden and systems with not enough human oversight and override for exceptional situations.
Of course, "touch grass" works just as well.
