Advocates for Trans Equality has an excellent page for submiting comments on the proposed passport changes. And, comments can be submitted anonymously! (ACLU has links to the pages to submit comments in their article, but I personally found A4TE's page much more helpful.)

> Our strategy? Our community and supporters should submit as many comments as possible to all three portals. This will show massive public resistance, potentially leading to media attention and increased public awareness, making it harder for them to push these changes through. Each step is critical, and once you complete one, we’ll direct you to the next.

> Remember, the more comments we submit, the more difficult it will be for the government to deny us our rights. Your voice matters, and together, we can make a significant impact!
