In the old days, things we didn't understand we labeled as magic.the sceptic said:Which hypothesis makes the fewest assumptions? Froome is doping, or Froome is clean?
Apple dropping from a tree? Magic
You dare to assume the earth is round? Magic. Burn the heretic!
It's much more easy on the mind to assume that all we do not understand is magic, or in this case doping.
Just because something takes a little more thought, and perhaps assumptions doesn't mean it is wrong.
