The goalposts are stationary and haven't moved a millimeter. It's cut and dry, you stated "I don't condone inappropriate behavior by Joe Biden" The videotaping of the offense is proof that the pedo engaged in inappropriate behavior, period. This, you cannot deny. And, to continue to support this perverted, demented individual would be a contradiction of your statement.
Stand by your word, condemn his inappropriate behavior with children or be a hypocrite. It's just that simple.
