Gravitating from "otherwise healthy" to visibly impaired cannot be compared to acting on gender dysphoria, where no one intentionally seeks disfigurement and where, for example, a mastectomy might be regarded as enhancement and unity, as the article pointed out.

Now, if someone wants to be transabled or a furry or whatever, it's their business and I don't really lose sleep over it.
