The moment he would admit to being Q
Would be the end.
Media would have a lifetime worth of ammo on him. Anit-(XYZ), Aliens, Jews, Hitler, Satanists, Cult, porn, you name it. It's all here and it would all be stapled to his name.
I don't think when he mentioned reporters asking the right questions this is what he had in mind.
More like, "Is so and so in custody?"
"Was there an assassination attempt on POTUS or First Lady"
Questions like this.
Not "Are you Q"
That's such a distraction
And it would be the instant end to Q
