Let's do an INTJ
Criticism only works when someone's willing to listen to them. Otherwise, you'll be hitting your head against a brick wall. If you want someone to listen, you must speak in their language unless their fluent in yours.
Criticism qualifies as racism when it unjustly interferes with your decisions. (Ex: Rejecting someone based on preconceived biases over their actual abilities.) But remember the manner in which a person defines as "criticism" or "racism" is mostly a subjective analysis that may not be applicable to everyone and every situation.
However, we can never escape the confines of our judgment because the world is inherently colored by our perception (made from personal experiences, desires, values, character, etc.). Yet we can use this judgment to criticize our own that leads to the creation of a superior one. Without being critical or having a judgment, this becomes virtually impossible to do and we can never progress as an individual or society.
