Very important to distinguish between liberal and leftist. Liberal thought is primarily performative because the underlying material(read: systemic) change necessary shall not be implemented, so lip-service like land acknowledgements, while by no means bad, is not nearly enough to mend historial wrongs and serves primarily today to distract from that material change. Reddit is broadly liberal, so the general populace cannot distinguish between "land acknowledgements are bad because [racism]" and "land acknowledgements are a 0th step towards progress" and remain liberal.
