I believe we didn’t accept abstract as art for so long because it was different. When things are different we often (as humans) avoid it or think less of it. In this case it’s art. People often think there is a handbook to creating art. But there isn’t which is why abstract art was not accepted. You had to develop a story for it instead of it developing a story for you.
Hope this helped!!
