The only people who are going to follow corsi now are boomers, I've been into conspiracy research over a decade and there's a lot of phonies in this field, opportunists, snake oil salesman, etc. You'll never find someone you totally agree with though so have to get bits of truth from people who have investigated on their own and compiled good data from other researchers while giving them credit. Corsi never caught my attention, never really had anything to add to the conversation and now it's clearly riding the q wave in order to gain attention from controversy.
Any publicity is good publicity to him so he simply changed his public opinion like a chameleon since being called out and now will bad 8chan and q and gain some left leaning followers who like what he has to say.
