They don't want the wider Asian communities as they exist now.

The 'stop Asian hate' stuff isn't much of an appeal to the wider communities but more a push to see if they can indoctrinate a few fringe members into the racial grievence con. Who will in turn help infect the rest of the community and turn them into the kind of blind cultists they do want. If you're running a con based on racial victimhood, the first thing you need are some evangelists of the right skin colour.
