Hate to pull the "been here since day one" card, yet, here it is.
I'm big on faith, yet not on blind faith and/or belief simply because another believes. Q posts which were as anon on 8 have been verified here via IP hash. So, w/o IP hash confirming, No, i don't simply "believe" that it's Q, regardless of how great the digits or the content may be. A skeptic needs to be convinced.
Having said that, i'm no cynic. i did have a thought that the post in ? may have been POTUS himself posting, YET, w/o sauce, it's not something I would advocate & try to make others believe my unsauced thought. That's how the R shit got started, and the confirmation bias which followed and continues to this day.
Again, IP hash sauce, or i don't buy it. That simple.
