This quote doesn't seem particularly anti-transgender. It definitely challenges the notion that identifying as transgender is the same as having gender-dysphoria.
Quote:"There is no scientific evidence that all transgender people have gender dysphoria, or that they are all struggling with their gender identities. Some individuals who are not transgender — that is, who do not identify as a gender that does not correspond with their biological sex — might nonetheless struggle with their gender identity; for example, girls who behave in some male-typical ways might experience various forms of distress without ever coming to identify as boys. Conversely, individuals who do identify as a gender that does not correspond with their biological sex may not experience clinically significant distress related to their gender identity. Even if only, say, 40% of individuals who identify as a gender that does not correspond with their biological sex experience significant distress related to their gender identity, this would constitute a public health issue requiring clinicians and others to act to support those with gender dysphoria, and hopefully, to reduce the rate of gender dysphoria in the population. There is no evidence to suggest that the other 60% in this hypothetical — that is, the individuals who identify as a gender that does not correspond with their biological sex but who do not experience significant distress — would require clinical treatment."
