No, I find it a meaningless policy because I'm not aware of a political party that says it is opposed to free speech. Basically, this is a list consisting of nothing of substance.
The party's more detailed manifesto is linked right there on the Policy page.
Do you realize you're posting this claim that all the parties are for Free Speech on the very day Tommy Robinson was arrested and jailed for simply being outside a court peacefully reporting on a grooming gang case that the establishment doesn't want reported on?
Is it the U.K. or is it Iran??
Not only do the establishment parties oppose Free Speech, they've already gotten rid of it. They just haven't started going after you for your views yet, so you don't care.
