I try not to believe anything if I can help it. It keeps me from thinking I know things for sure that are probably bullshit like you. It's probably Biden and Clinton unless there is some exotic technology like holograms or cloning or genetic morphing going on that we don't know about. There is strong chance Mike is a dude. Those child age photos look very female though. I have not seen an explanation for that.

There is very little if anything we can know for absolute certain. That's what I think. I see people get carried away with these replacement theories all the time and it's often associated with these kinds of overly sure attitudes; PIDers and people like that.
