Can you have expansion without contraction?
It's a meaningless question, because it's like supposing that all matter is expanding linearly (or otherwise) in scale. The most simple explanation is that it isn't.
Perhaps the OP postulates the question relating more to society than science? One can also analyze the word 'contradiction'. Does it mean the opposite of expansion, that is, some form of compression, or does it mean that expansion in a field in society will lead to it being contradictory?
Can something go left without going right?
Has the universe ever gone through a period of contraction, since the Big Bang?
