Yor eager willingness to accept a lot of nonsense as "truth" pretty much excludes you as any credible arbitor of what is or is not fact. I have no doubt you "believe" you know truth. It is probably better for you that you go on believing things are as you wish them to be. As long as you are in no particular position to enforce your beliefs on me it is no real concern.
What is nonsense?
There are several similar definitions of "nonsense". Here is one I like:
"words or actions that convey an absurd meaning or no meaning at all; things of relatively no importance or value; trivialities; impudent, foolish, or evasive behavior"
Yes it is nonsense to deflect away from the point that Romney is a mirror image of obama.
