For me, I had been all over the net cheering for DJT in the primary season and then, of course, the race against Cankle bitch from hell.
Was also looking into Seth and the DIMocrats, RINOS - Mueller, McCain, etc. and their parts in the shit fest.
One night I was on 4chan sharing digs when another poster came on with what seemed to be insider information. That's how I became a Q follower.
I like to bounce between /x/ and /pol/ when I get bored, and during the 2016 election, the memes were particularly spicy, that and back then FBIAnon was a thing. I remember those first few posts, it took a while Q to learn how to communicate with Anons, no one really took those early posts very seriously at the time, but persistence, as they say, pays off, and here we are.
