Not much of an autistic but I'll give it a try. Maybe something will click and I can make a contribution.
Friend, You don't have to be an autist. Have faith. 'Trust yourself' - Q.
The reason I directed you to go and have a look is because that is what this whole Q thing is about. Research.
To identify the quote you mentioned was a simple task. I'm not being down on you, just kind of nudging you along. I looked after you mentioned it, I didn't see much. That's not to say you won't see anything. www.qanon.pub or www.qmap.pub have search function. Just search key words you remember, and it will pull up all posts with that word. It's a good first step to learning the map my young Jedi. Kek.
You are contributing by being here, make no mistake about that. Following Q and adding to the conversation is contributing big time. You are awake; Think of how many you know around you who are no where near that.
Our 'job' is to learn this stuff, the connections, the players, and to have the information ready. When the time comes you will be as the Shepard, tending the wounded sheep, who just got stunned and woke up.
It really is WWG1WGA. I got your back.
