I've got two theories regarding David Icke and his Reptile bullshit.
1. He's a plant out to delegitimize all dissent or alternative theories.
2. He knows stuff and keeps talking about fucking reptiles to throw the establishment off his scent, so he can talk about relevant topics without getting deplatformed/censored
Hes just batshit crazy, nothing more to it then that. Hes a functional coherent schizophrenic, the most extreme case of a coherent schizophrenic i can think is Russell Eugene Weston(google it)
