Also, what about a pistol, carried on your person as you go about your day? Here in the US it is generally possible to do that. (variation by state: concealed carry may need a license, open carry may need a license, some states prohibit using it unless you can't retreat, etc.)
The problem with guns are virtually none existing in the UK.
In the US, the 1st Amendment expressly prohibits this kind of authoritarianism.

But regardless, you've conveniently only quoted part of that law text. It's only about electronic communication https://www.legislation.gov.uk/ukpga/2003/21/section/127
and for context the relevant parts read:
With 1a saying
A person is guilty of an offence if he sends by means of a public
electronic communications network a message or other matter that is
grossly offensive or of an indecent, obscene or menacing character
and 2a saying A person is guilty of an offence if, for the purpose of causing
annoyance, inconvenience or needless anxiety to another, he sends by
means of a public electronic communications network, a message that he
knows to be false
In other words, you're not allowed to lie for the sole purpose of "causing annoyance, inconvenience or needless anxiety to another" and you're not allowed to send messages that are "grossly offensive or of an indecent, obscene or menacing character". 1a is not allowed under 1st amendment, and we can argue about how the latter is allowed by the 1st amendment, but some of it surely isn't as obscenity, incitement, and fighting words and offensive speech are explicitly not allowed.https://www.coe.int/en/web/conventions/full-list/-/conventio...
