Then I'm sure you're also familiar with the ransacking of Hirschfeld's Institute for Sexology in 1933, where some of the first treatment plans for trans people were developed. It was a place where gay people and trans people were accepted and treated with respect by medical personnel.

That famous picture of the book burnings? Those were patient records and the research archives of the institute. So no, it did not just start with gay people, and trans people's persecution by nazis was relevant to bring up because it's one of the first kinds of persecution the nazis did. Dismissing that is ahistorical and dismissive of the history of oppression of trans people.
