I've read a lot of the "evidence" that has been presented on this topic - it's madness.
Most of it seems to rest on proving the scanned document we've seen is a fake because the mechanically printed lines in it don't line up to the pixel. Considering the birth certificate was printed almost 50 years ago with a mechanical typewriter and then scanned, I'm surprised the lines even line up to within a couple of pixels. Neither my birth certificate nor others I have seen have text that's completely straight.
If you have any actual evidence, please present it, otherwise stop.
