While not directly applicable here (the article mentions QAnon policies but I'm not sure how close that particular group was to the ideology), in general I also believe calling QAnon "political speech" is a bit of a stretch. "Insanity" is what it should be called and should be dealt with by pointing them to counselling & mental health support services, not giving them a platform to publish their stupidity and grow an audience. That clearly isn't happening as Facebook is happy to profit off all these crazies and give them a safe space to communicate - the groups will only get shut down when and if the negative PR impact outweighs the profits.
