That application of psychedelics is almost entirely dissimilar to what you are proposing. While a lot of the emerging research in the field is nice (and long overdue in my opinion), I would be absolutely floored if any of it recommended DMT for the treatment of dissenting opinions.

It's not like I just also could use some DMT either, since I already use psychedelics on a damn near weekly basis. It's just not something that you should be telling random strangers to try. It works differently on everyone, is not always helpful, and can even be harmful.
