To liberals, holding the right opinions is praxis. Having done their "praxis", they can use it to bludgeon actual leftist praxis, lest you interfere with the benefits their performance provides.

They achieve not trans, indigenous, or queer liberation, but a feeling of superiority and self content that provides enough moral licensing to justify whatever bastard shit they need to excuse. Being a good opinion haver™ lets them continue doing nothing with their ego unscathed.

This strengthens the dialectical relationship between doing nothing & reaction, effectively putting action in the corner. Status quo maintained.
