Oh of course there are.  The speciesism in Papi’s canon runs both ways, and among many it runs very deep.  Celestia is an example of this as she has only known changelings to be destructive, and deceitful, and from her earliest experiences with them was given reason to believe that they are a blight upon the land, and must be eliminated to protect her subjects, just like Discord.

The actions taken to do so led many changelings, especially in later generations to believe that Celestia is no more than a hateful tyrant, and that ponies are monsters who only want changelings to suffer, or to die.

Any peace talk that could possibly take place would not see all of these feelings expunged, even if things are changed on the surface.
