I think Samson has fallen for those who are opposed to the law and how they have misrepresented what it says. Scotland already has this law
https://www.legislation.gov.uk/asp/2010/13/section/38
"38Threatening or abusive behaviour
(1)A person (“A”) commits an offence if—
(a)A behaves in a threatening or abusive manner,
(b)the behaviour would be likely to cause a reasonable person to suffer fear or alarm, and
(c)A intends by the behaviour to cause fear or alarm or is reckless as to whether the behaviour would cause fear or alarm."
And this law;
https://www.legislation.gov.uk/ukpga/2003/21/section/127
"127Improper use of public electronic communications network
(1)A person is guilty of an offence if he—
(a)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; or
(b)causes any such message or matter to be so sent.
(2)A person is guilty of an offence if, for the purpose of causing annoyance, inconvenience or needless anxiety to another, he—
[F1(a)sends by means of a public electronic communications network, a message that he knows to be false,]
[F1(b)causes such a message to be sent; or]
(c)persistently makes use of a public electronic communications network."
The Hate crime act just adds on to that, for the purposes of spreading hate regarding people due to their religious beliefs, sexual orientation etc. How that will work in practice has yet to be seen, but some are being deliberately mischievous, by suggesting any form of criticism is now illegal, or in JK Rowling's case, lots of people are predicting she will go to prison because she has referred to trans women as men.
But the prosecution has to prove hate, rather than being critical, which is a defence under the Hate Act.
