There are very few situations where speech leads to incarceration, and I don't think PG is talking about those, is he?
Usually when people complain about what you "can't say", what they actually mean is they can't say whatever they like and still have people still employ / socialise / be nice to them.
Expressing opinions that others find disagreeable is not a protected class.
If you want to shun me for not loudly enough pronouncing how great some sort of special privileges for certain ostensibly oppressed classes is, or for not jumping enthusiastically enough though hoops referencing people with exactly the most woke-community prescribed terminology, then chances are I don't particularly to associate with you either. That's fine.
If you start telling lies about me online and try to incite a mob to threaten or harm me and the people who do opt to socialize with me (despite or maybe even because of my opinions), or organize mobs for PR damage to pressure my boss into taking away my livelihood, that is something quite beyond exercising your right to choose your associations.
Of course that would still not literally make me unable to pronounce my woke-taboo opinion, but it should nonetheless be obvious that trying to wreck my life is a disproportionate response merely to me not toeing the line you took it upon yourself to draw. What you "can't say" is almost always graded rather than absolute, but active hostility destroying months or years of a person's life is well into the territory that constitutes a real hindrance for freely expressing an opinion.
