What do the Suttas say about restricting questions or discussions

In one sutta the Buddha says to the monks that if they’re not discussing Dhamma then they should maintain “noble silence” (possibly this silence is a reference to meditation), and in various other places he cautions against idle chatter and discussing mundane issues. They are referred to as “Animal Talk (Tiracchāna Kathā)”, 32 in number, about such topics as kings and government, wars and armies, thieves and dangers, foodstuffs, clothes, perfumes and jewellery, etc.

Which, as I understand it, means that monastics should not be discussion topics variously known as engaged Buddhist action, social activism, social justice, etc.
Which a number of monastics frequently do.
