Shelby, Gio is quite obviously not claiming that Hussie is running a secret Jubilite cult and that Psycholonials was made to indoctrinate people into hater-hunting assassins. I believe the point being made is that he was willing to overlook the fact that prior Homestuck employees had whipped up fans directly, telling them in no uncertain words to 'get this bitch' and 'rip him apart' (and these fans may have done so under the auspices of 'Jubilism' - presumably ironically, although if you're making death threats, you're not smart, so who knows?), but Hussie was not willing to overlook the fact that WhatPumpkin received hate for their own actions, that he believes Gio to be at fault for.
