There is a difference between someone's opinion and something that is offensive and potentially conspiring or inciting a crime. "I hate Boris because he doesn't run the country properly" could be called hateful but wouldn't be taken seriously by anyone, whereas, "We should kill Boris because he doesn't run the country properly" is at least borderline. I haven't seen many examples of something that would be considered criminal but look like they should be covered by "free speech" laws i.e. examples where a legitimate statement of opinion would be considered illegal.
