This is gatekeeping via transmedicalist talking points.

Dysphoria is not central to the trans experience. It's central to some trans experiences.

Even if your belief that dysphoria has biological/medical routes were true, that still doesn't mean that it's the only way to be trans.

Whatever else it is, gender is also a social construct, and our relationships with social constructs shape who we are in very real ways.

And hell to take your gatekeeping ever further, even if you're right, and some trans folk can "stop being trans" as a result of their social environment or whatever, they're still trans until they're not.

This is about the time that people (typically) stop the conversation and try to get you banned by calling you truscum and transphobic.

Yep, for good reason
