I can give you some examples of misinformation presented as science. One, Wakefield's theory that vaccines cause autism. Two, Australian anti-abortions claiming that abortions increase the risk of breast cancer. I'm glad you don't have anything against the trans community, so maybe it's best to say, "If that's what the trans community want to do, that's fine, as long as they are advised correctly by their doctors and are monitored closely."
