Tucutes believe gender dysphoria isn't necessary to identify as transgender. A minority of tucutes may even argue the possibility that gender dysphoria doesn't exist. This is not to be confused with non-dysphoric trans people, because many tucutes do indeed have Gender Dysphoria. There are many links and reasons as to why tucutes believe this, and was not decided on a whim. The lack of scientific evidence for both sides makes this debate complicated, but it's just that; an opinion. It is not worth attacking someone over.
