I imagine grandparent is referring to an incident in the UK where a man was arrested for “silently praying.” The additional context is that he was in a legally mandated exclusion zone around an abortion clinic.

It’s become a meme (sans context of course) in conservative circles since Vance recently reiterated it. Never mind that the US uses such free speech exclusion zones frequently.
