This is a oversimplification of something that is much more nuanced. Ask gay people if anything has changed, or African Americans, or women, or people who benefit from new medical or technological advances...of course in one way or another there is an argument to be made from your position but it is not accurate, or productive or useful in any way that I can see. It is kind of like ageing.
You dont notice the little changes day by day as you age, it is incremental and slow but change is occurring none the less. Look at a photo of yourself 5 0r ten years a go. I think it is the same for us on the whole, it might be a step backwards one day, two steps forward another, but looking at the big picture you cannot deny that change is a constant. How fast and in what direction is up to the people who are willing to do the things that make change happen.
