nobody's required to deny anything. i however do not believe in liars (al gore and obama) and evolution is only a theory, not fact...just like man made climate change.
when they are clearly misled, then yes, tell them the truth.
i can see how the global warming thing is a bit crazy but the health care one is true: if u don't get government health care, you'll go to jail. so, its ur choice...join socialism or go to prison. its the first time i've heard that...
because its so idiotic that even if states opt it out, the people of those states STILL have to pay for the damn thing! how could the liberals even think that ANYONE opposed to the original idea would agree to this madness? sheesh, are they really that stupid?
