Never has been.
Never will be.
Liberals know things that the rest of us find hard to believe. For example: liberals know that there are an infinite number of correct answers to the question, "2 + 2 = ?". In fact, to them the only incorrect answer is "4". They know this because they shopped around until they found a judge who confirmed this and then they made it a law based on a consensus of Democrat legislators.
There are. 8-4, 2 squared, the square root of two to the fourth, 5-1, 100/25...you get the idea.
