Even if Q is legit, they are not going to always be right. They are not Gods or time travelers. They also are going be be "debunked" by many people close to the president. If it is legit it is a VERY clandestine operation that less than ten people are fully in the know about.
We can't always jump to conclusions about their legitimacy because something doesn't go the way Q planned it to or because someone close to POTUS denies it. The people in high offices have always removed themselves from anything that looks crazy in order to protect their public reputations whether or not they actually believe in it.
I do believe and always have but I have been questioning it more lately. I am ESPECIALLY troubled by the posts about Q=Alice, then Alice in wonderland/ Hillary in wonderland. If Q= Hillary and this is a dem psyop l dunno if I'll ever believe in anything again
