I can try..
Q claims to be "draining the swamp"; ridding the US of the "shadow government"; cleansing the world of corruption and/or evil; destroying the CIA & other alphabets; plus whatever else they say.. Etc
But the main theory of the .pdf suggests that rather than JFK being murdered because he wanted to do similar he was first and foremost an integral part of the shadow government and even going so far as to claim the death of JFK was faked so a shadow presidency could be created where all POTUS's since JFK have merely been the puppets of the shadow POTUS
Like I said before, if only half the theories within the .pdf are correct (and it is fairly convincing in some respects) then who/what Q is is not who/what we anons think he/they are
I suggest reading the .pdf first then making your own mind up as to how credible the theories within might be and how it impacts on how you view Q
