Convince nationalists that some magical savior was going to do everything for them so the nationalists will get lazy (sap their motivation to do stuff for themselves, especially volunteer investigations of election fraud, spreading information and flyers supporting Trump or exposing the establishment, etc). Why bother when Q will fix everything for you? Just sit back, relax, "trust the plan" and do nothing.

Cook up an artificially manufactured image of their political enemies as mentally ill losers so that normal people from the public will be less likely to listen to nationalists in general or join them. It's a form of forcefully rebranding your political enemies and creating controlled opposition. It's not an accident that they chose a LARPing cosplayer as one of the supposed leaders and MSM named him the Q anon "shaman". They're trying to turn nationalism into an unserious circus using dishonest rebranding. Now when the public hears someone criticizing the establishment, they will get the image in their head of some theatrical dressed up lunatic "storming" the White House, instead of a serious intelligent well spoken individual in a suit and tie. This stuff matters a hell of a lot in a propaganda war. People who dismiss this stuff and accuse those who care of being "optics cucks" are strategically braindead. Propaganda wars are all about optics.
