I wouldn't think of it as an ideology. I mean, maybe it is, but it doesn't seem at all bizarre. I'm not really aware of the details, but I'd be hard-pressed to name a difference between the two. I don't (think I) have a position on the issue.
But trans means switching from one side of the binary to the other, while dysphoria means "unease or dissatisfaction" which is not at all the same. One can easily be uneasy or dissatisfied with one's perceived gender identity yet not want to switch to the other side of the binary. What about agender people, or people who just don't like gender at all?
I certainly remember as a teen being unhappy with the constraints gender put on me in social situations but that certainly doesn't mean I'm trans.
There is a semantic shift taking place in the scientific community regarding the use of the prefix trans when referring to sex (physical anatomy) reassignment as a treatment in gender affirmative care.
Unfortunately, politics keeps interfering with the word choices of scientists.
