NEVER! He's a patriot! Plus..
1) There's no way he is in on what is up with his dad. He's as clueless as everyone else. He's guessing.
2) Read his post CAREFULLY. His language was VERY specific. He didn't actually "denounce" Q, he said he was not associated (true), Q is a conspiracy (true), and that he doesn't follow the "#Qanon hashtag" (a good idea) and none of us should either (I don't anymore).
2) corollary: The #Qanon hashtag is a shitshow. You won't get any real information regarding Q from that search since it is populated by every shill and concernfag you could ever imagine.
