Whether or not they view it as something to be proud of depends on the transmed. They do recognize that they have a disease, but they define that disease in terms of 'my brain doesn't match my body and causes me physical distress.' They also say things like 'I knew from a young age I was really male/female', which again, is directly tied to their belief in brain sex. They often reference that gender dysphoria is considered a real disorder in the DSM-5, and use this to back their beliefs that they are more legitimate than trucutes. However, if you look on psychiatry.org and how the American Psychiatric Association defines and diagnoses gender dysphoria, this is what is says:

A marked incongruence between one’s experienced/expressed gender and primary and/or secondary sex characteristics (or in young adolescents, the anticipated secondary sex characteristics)

A strong desire to be rid of one’s primary and/or secondary sex characteristics because of a marked incongruence with one’s experienced/expressed gender (or in young adolescents, a desire to prevent the development of the anticipated secondary sex characteristics)

A strong desire for the primary and/or secondary sex characteristics of the other gender

A strong desire to be of the other gender (or some alternative gender different from one’s assigned gender)

A strong desire to be treated as the other gender (or some alternative gender different from one’s assigned gender)

A strong conviction that one has the typical feelings and reactions of the other gender (or some alternative gender different from one’s assigned gender)

A strong desire to be of the other gender or an insistence that one is the other gender (or some alternative gender different from one’s assigned gender)

In boys (assigned gender), a strong preference for cross-dressing or simulating female attire; or in girls (assigned gender), a strong preference for wearing only typical masculine clothing and a strong resistance to the wearing of typical feminine clothing

A strong preference for cross-gender roles in make-believe play or fantasy play

A strong preference for the toys, games or activities stereotypically used or engaged in by the other gender

A strong preference for playmates of the other gender

In boys (assigned gender), a strong rejection of typically masculine toys, games, and activities and a strong avoidance of rough-and-tumble play; or in girls (assigned gender), a strong rejection of typically feminine toys, games, and activities

A strong dislike of one’s sexual anatomy

A strong desire for the physical sex characteristics that match one’s experienced gender

This speaks to the fact that most transmeds/trucsums look at gender nonconformity as signs of transness, and do not take it at face value. 'A strong conviction that one has the typical feelings and reactions of the other gender' is a criteria that is used to diagnose dysphoria. What does that mean, exactly? Well, nothing, unless you believe in brain sex and that certain thought patterns are innately male or female, which transmeds support.

There also isn't a good way to separate body dysphoria from a belief in brain sex. If that separation existed, we'd see more GNC people with dysphoria who say things like 'I altered my body to look like the opposite sex, but I'm not actually a man/woman. I'm a GNC person with dysphoria.' However, transmeds don't say that. Transmen (like Kalvin Garrah for example) might say 'I may be female, but I know in my brain I'm a man.' Transwomen like Blair White might recognize they're male but will still imply 'for all intents and purposes I'm a straight woman, because I look like one.' Blair in particular also references the DSM-5 criteria quite a lot in his videos to drive the point home that gender dysphoria is a mental disorder. We can give Blair a point for grounding his beliefs in reality, but what does that say about his views on GNC behavior? It's regressive because he thinks that a strong preference for the clothing, toys, hobbies, and social roles associated with the opposite sex means you may as well transition.

Transmeds are also usually homosexual, and as a result are often very homophobic because their internalized homophobia that led them to transition usually becomes externalized over time. Sam Collins is a lesbian who became a transman partly because, in her own words, she 'didn't want to be a girl who liked girls' she 'wanted to be a boy who liked girls.'

Other TRAs don't like transmeds because they see the requirement of gender dysphoria as gatekeeping others out of being trans, not because transmeds are more sensible. Transmeds' beliefs are regressive, sexist, and homophobic.
