Wow, I've actually had two people email me that video in the last couple days.
OK... let's assume they've figured out time travel in the future, and not only that but apparently precise, safe time travel, which would be infinitely more problematic than time travel itself. So they can send actual human beings through overlaps in space time, maybe in or around a black hole, and manage to keep them alive and not crushed down smaller than an atom and placed when they want them, and even trickier, where they want them.
Assuming they've figured this all out, i'm betting they're also not dumb and/or completely insane enough to travel BACK in time. And if they are, they would make sure somehow not to effect the timeline, which would be practically impossible. And they sure as hell wouldn't be walking down the street like assholes in front of movie sets and interacting with people and creating literally millions and billions of alternate time-lines stretching out into infinity and creating and erasing millions of future beings with every step they took. Anyone who travels back in time risks destroying their own timeline and everyone's they know.
If you assume that the time travelers have traveled back in time with the intent to change the timeline to prevent some future event, which would indeed be the only reasonable explanation for them being there, they still sure as hell wouldn't do it by strolling down the sidewalk dressed in drag looking like a freak.
So yeah, it's not a time traveler, you rough ridin' fucks.
