Your post does not go far enough. You must not only approve, you have to promote the idea in question.
YOU ARE CORRECT!
I must update my previous explanation;
Its all about Tolerance. (ver 2.0)
To a Conservative the word tolerance means casual indifference.
To tolerate something means to ignore it, or at least not actively oppose it.
But to a Progressive the word tolerance means celebratory approval. Casual indifference is not good enough! Even ‘friendly recognition’ is insufficient. Tolerance equals active promotion of a given position. To display anything less than 100% agreement is to risk being referred to as Intolerant. To be called Intolerant is to risk being considered a Hater. And to be branded a Hater is a fate worse than death to a Progressive.
