The four words you're referring to are "I support Palestine Action", and there's nobody in prison "for a long stretch" just for saying that.

There have been over 3000 people arrested for showing support for this proscribed organisation, and over 700 charged, but none actually prosecuted yet. It was only just decided two weeks ago that the government's act of proscribing Palestine Action was lawful.

Obviously, I think the Terrorism Act shouldn't silence speech like it does. Palestine Action are a pack of bumbling thugs, and the government's real reason for proscription is that those idiots successfully broke into an RAF base. Egg on face for military so government strikes back with proscription.

The law does allow for these sorts of penalties you describe. But I think you will find that if the CPS does prosecute these cases, especially against people who literally stood in front of police stations and displayed those four words and no more, i.e. they dared the government to prosecute them for speech, I don't think they will be "put in prison for a long stretch". They may not even be prosecuted at all. They would have to do more, i.e. actually break into places and physically damage them, like Palestine Action have repeatedly done, to get a long prison sentence. But the threat of prison for speech is there in the law, that's why I don't like that law.

You shouldn't be judged based on your speech, only your actions. That's the problem with the Terrorism Act.
