No, no, no. What you had stated is your view point based on your experience and perception, but you can not stated that your view point is the truth.
Under your perception you might feel that your government has many progressive policies towards the minorities, but the recipients of such policies might have a totally different point of view based on their own perspective.
From my understanding is that culturely the Chinese are always very discriminating towards the minorities, that’s why your article is called “Han Chauvinism”, and all the Chinese governments are very chauvinistic as well in their policies or attitudes, always has been and still is.
These kinds of trends can be seem not only from the posts on your forum, but the same can be observed in Taiwan. To preserve the minority culture and their identity is not as simple as giving them some tax benefits then called it progressive policies. It has nothing to do with it.
